Ducks lay eggs. Except when they don’t.

Why aren’t my ducks laying? Why did my ducks suddenly stop laying? When will my ducks lay? Shouldn’t my ducks be laying more eggs than this? It’s one of the most frustrating issues people have with their ducks, and also one of the most frequent complaints I hear.

The definitive answer is here. Every “my ducks aren’t laying eggs!” case I’ve ever heard of can be attributed to one or more of these fifteen causes:

  1. She’s not old enough.
  2. She’s too old.
  3. She’s actually a he.
  4. The days are too short.
  5. The weather is too extreme.
  6. Something is stealing the eggs.
  7. She’s hiding the eggs.
  8. She’s eating the eggs.
  9. She’s randomly laying the eggs wherever, rather than in a nest.
  10. She isn’t getting the nutrition she needs.
  11. She’s molting.
  12. She’s broody.
  13. She’s sick.
  14. She’s stressed.
  15. She’s obese.

Let’s go into a bit more detail.

She’s not old enough.

Ducks normally start laying around five to six months of age. Some people expect them to mature earlier. Also, just seeing your ducks mating doesn’t mean they’re ready to produce eggs, because drakes are able to mate before female ducks are ready to lay. Read “When do ducks start laying eggs?” for more.

She’s too old.

If you bought adult ducks from someone else who didn’t mention their age, it’s possible they’re too old to lay. Or if your ducks have been laying less and less as the years pass, it’s because they’re getting older. Ducks lay the most during their first year, and gradually slow as they age. By four or five, they probably won’t be very productive. By seven, they may have completely stopped. Keep in mind that it varies a lot and these are just averages. I currently have six-year-olds that still seem to lay quite well, and some people have ten-year-olds that still lay. Read “When do ducks stop laying eggs?” for more on when ducks stop laying.

Keep in mind that your duck hatches with all the eggs she will ever lay already inside her. This means that technically, you can’t make your ducks lay more (through artificial lighting and other techniques). You can only make them empty their supply faster. If you’ve been pushing your ducks to lay as fast as they can, they will run out of eggs sooner. This also mean that ducks such as Khaki Campbells will stop laying sooner than something like an Aylesbury. You can’t expect your duck to lay steadily for 5+ years if it’s a Khaki Campbell that has been eating a high-protein diet and been living in artificially extended days. She might have to call it quits by three.

She’s actually a he.

Are you absolutely sure your ducks are females? Sellers aren’t necessarily trustworthy. Last year, I bought four geese from a lady who claimed the all-gray geese were females and the saddleback (part gray, part white) ones were males. There are a few breeds of geese that you can sex by color, but I was suspicious because I didn’t think ours were one of those breeds. Sure enough, one of the saddleback geese started laying not long after we got her, and both of the gray geese were ganders.

Read “How to Tell if Your Duck is Boy or a Girl” if you’re not sure how to tell whether your ducks are males or females. If you have Muscovies, read this article: 10 Effective Ways to Sex Your Muscovy Duck.

By the way, have you ever actually witnessed a duck laying an egg? Here’s a closeup video of my two adorable Muscovy duck sisters, Peaches and Mitzi, laying their eggs:

The days are too short.

I think this is the most common answer to the complaint, “My ducks aren’t laying!” There are very few breeds of ducks that will lay all year round, and even those don’t necessarily lay if there isn’t enough light. Ideally, ducks need 14 to 16 hours of light per day in order to lay at their maximum potential. Many flock raisers get around this problem by giving their ducks artificial light to lengthen their “day.” Here’s information on giving artificial light to your ducks to boost their laying: How to Use Lights to Increase Duck Egg Production.

In some locations where days get very short, ducks only start laying during their first spring after they’re old enough. For example, if they hatched in March, they’d be old enough to lay around September, but by that time the days would be too short, so they would only start the next spring, most likely only after all the snow has melted. Even more extreme, but not impossible, would be a duck that hatched in January, is mature enough to lay in June, but doesn’t start laying until next April—when she is sixteen months old!

Some breeds of ducks are seasonal layers and only lay in spring no matter how long the days are. Many meat breeds and other breeds not bred for extreme egg production are like this. Mallards, for example, will likely only lay two or three clutches a year, all in spring.

Even if the days should be long enough, are your ducks kept in a dark barn or coop? If their living area is too dark, they won’t know when the sun comes up, and thus the day will seem shorter and they may not lay.

The weather is too extreme.

Temperature extremes will prevent a duck from laying. If you live in an extremely hot climate or if your ducks don’t have adequate shade or constantly-available cool water, they may not lay much. Cold also influences their laying. Muscovies are especially sensitive to cold and it can be difficult to get them to lay if there’s snow on the ground.

Even just ordinary weather changes can temporarily mess up laying cycles. I’ve noticed that our ducks lay less if we’re having a cloudy or rainy spell, although that could just be because the sun is covered in clouds and thus it seems like it takes longer to rise.

Something is stealing the eggs.

Here’s another major cause. Our German Shepherd puppy, Nora, quickly became an egg thief once she started discovering nests, although we were able to nip the habit in the bud. Foxes have also stolen many, many of our eggs.

If your ducks free range (like ours), this is a likely reason. To prevent foxes or other animals from stealing the eggs, keep your ducks locked up in a coop until they have laid their eggs. What time they lay varies a lot, but most ducks will be finished laying by 8 AM. Read “What time do ducks lay their eggs?” for more. If you go to work before this time, you might consider investing in an automatic coop door.

Unfortunately, some ducks are so desperate to lay in whatever hidden nest they deem superior to what they have in their coop that they will hold their eggs until they are let out, even if it’s past noon, so keeping them in the coop isn’t necessarily foolproof.

Even if they are in a coop all morning and/or spend the day in an enclosed run, be sure that there are no gaps that an animal could slip through. Even small animals such as mice, rats, and snakes can be thieves. You may need to predator-proof your coop.

She’s hiding the eggs.

Your duck herself is an even more likely culprit than a wily fox. She may be laying, just not where you expect! It’s hard to convince some ducks that your nest is the best place to lay. My ducks have laid eggs in wheelbarrows that were covered and I thought could not be entered, clumps of thick grass (saw grass, at that!), bushes on the neighbor’s property, under tarps, and pretty much any hidden, dark area they could find. One of mine even thought about laying inside an empty cement mixer. Here’s an article I wrote on defeating those sneaky ladies who hide their eggs—although I can tell you from personal experience that it’s pretty much impossible to completely prevent them from hiding eggs without taking away their free ranging privileges or at least keeping them locked up in a coop or run until noon.

She’s eating the eggs.

Ducks don’t normally eat their eggs. However, once upon a time, a duck might accidentally break one of her eggs. Then she tastes it and…yum! And it becomes a habit to break and eat all her eggs, and maybe also the eggs of other ducks. Here are two articles on Backyard Chickens about breaking an egg-eater. They are about chickens, but they apply to ducks as well.

Six Tips on Breaking Your Egg-Eater

Egg Eating: What are the Causes, and How to Prevent It

She’s randomly laying the eggs wherever, rather than in a nest.

Don’t assume that eggs will only pop up inside a nest box. Some ducks have zilch interest in nests, especially the ones that are the most prolific egg-layers, such as Runners and Khaki Campbells. They will drop their egg wherever they happen to be when they feel the egg coming. If they have a pond, they might be dropping the eggs in their pond. If they free range, the eggs could be anywhere in the grass. To be sure you are able to collect her eggs, make sure she stays locked up in a coop or small run until it’s late enough in the day that she should have laid her egg.

She isn’t getting the nutrition she needs.

A duck that relies on the food it gets from free ranging, or one that only receives “treat” foods such as lettuce and watermelon is not getting enough nutrition—especially protein—to regularly lay. Also, feeding plain corn, scratch, or any commercial feed with inadequate protein will cause problems. A laying duck’s diet needs to contain approximately 17% protein.

Of course free ranging is natural, and ducks in the wild don’t have any trouble laying. The problem is, they won’t lay nearly the amount of eggs we might expect, because today’s perfectly computed feeds have been crafted to squeeze out every egg the duck is capable of laying. In the wild, they only need a few clutches. If you want your ducks to find all their food free ranging, that’s great, but you simply cannot expect 300 eggs a year, because that’s an unnatural amount and can only be achieved through unnatural feeding.

Lack of calcium is another nutritional problem that can completely stop a duck from laying. Most flock raisers offer their birds free choice oyster shell or crushed eggshells to be sure they have adequate calcium.

She’s molting.

Ducks normally molt (replacing all their old feathers with new ones) once a year, and they can’t lay and molt at the same time, because both eggs and feathers contain high levels of protein, and it’s too difficult to produce both at once. Your ducks WILL molt once a year (usually in winter) and you can’t stop that. However, problems arise when a duck is taking too long to molt or is molting more than once a year. Ducks in regions with long periods of short winter days may take up to six months to molt. A diet with low protein levels will also prolong the molting period. A sudden shortening of days may also trigger a molt (for example, if you suddenly start putting your ducks in a dark coop before the sun is down, or if your artificial light fails). A very stressful event can also cause a molt.

She’s broody.

It’s easy to tell when a duck is broody. She will sit consistently on her nest, only leaving it to drink and eat once or twice a day. She will probably hiss and peck at anyone who comes near her. Ducks often go broody right after laying a clutch, even if you’ve picked the eggs. If you don’t break her broodiness, she’ll sit on that nest for the full 28 days required for eggs to incubate and hatch (regardless of whether she actually has eggs under her), and she won’t lay during that period or even for some time after. If your duck goes broody and you aren’t intending on letting her hatch any babies, you’ll have to break her up in order for her to get back to normal life and start laying again.

If your duck has just hatched ducklings, don’t expect her to lay eggs for at least two months. She won’t lay while she’s raising ducklings.

She’s sick.

Observe your ducks for at least a few minutes a day. Be sure they’re active, eating and drinking well, and in good health. A duck that sits in the corner with droopy feathers, not eating much, if at all, is probably sick, and probably won’t lay. Parasites will also prevent a duck from laying. Be sure to rule this out when trying to pin down the cause of the absence of eggs.

She’s stressed.

Stress will hamper a duck’s laying ability severely, or even completely prevent her from laying. Is there anything stressful that frequently happens to your duck–being chased, being picked up and petted or held a lot (some ducks enjoy this, but many don’t), being in a pen that is too small, enduring unhygienic living conditions, being bullied by chickens or other animals frequently, not always having water available, or something else? Being mated too often is also stressful, so it’s not recommended to keep ducks in pairs.

Sudden changes in her lifestyle, such as being moved from one home to another, will also cut off her laying temporarily. If you just got your ducks, don’t expect eggs until they’ve had time to settle down and get used to their new surroundings. Adding new ducks to a flock can upset and stress them all, temporarily, due to the pecking order changes.

She’s obese.

Some ducks are gluttons, and obese ducks don’t lay. Ducks, like humans, are perfectly capable and in fact quite likely to eat way more than they really need to. If she’s locked up all day with no ability to forage, with food available 24/7, she could be overeating. I recommend rationing your ducks’ food, as well as not leaving it laying around all day long, and instead giving your ducks two meals a day.

Also, feeding too many treats that have little nutrition, such as scratch, bread, and lettuce, will fill her up with food that doesn’t give her much nutrition, and thus she’ll use it for fat rather than eggs.

Troubleshooting Tips

When trying to pin down the exact reason your ducks are not laying, these are the main factors to consider:

  • Your duck’s age
  • Your duck’s breed
  • Your duck’s feeding habits
  • Where your ducks live
  • What time of year it is
  • What your ducks’ daily routine and living area is like

If you’re still not sure, contact me and I’ll try to help you. Be sure to list the duck’s age, breed, diet, and other pertinent information.

  1. I have an Indian runner. The seller said she is a year old. We got her in June this year. She is active, lively and comes when I call her name. She has not laid a single egg. I can rule out stress as a factor. Should I begin to worry? Thank you.

    1. Hi Donna,

      Is it possible for you to rule anything else out? I can’t help you a whole lot beyond the information in the article without more information. For example:

      1. Describe her living area. How protected is it? How large is it?
      2. Describe her schedule. When does she eat? Where is she during the day, and during the night?
      3. Describe her diet. What does she eat? How much does she eat? How often does she eat?
      4. Is she alone? Being alone IS stressful. I am not sure if lack of a companion is stressful enough to prevent laying, but I recommend getting her a companion either way.

      Try looking over the list at the top of the article again to rule out more possibilities. I can also try to help you more, if you provide a little more information.

      Often, ducks only start laying in spring regardless of age, although that’s rather unusual for an Indian Runner. Still, I wouldn’t actually worry unless she still doesn’t lay this coming spring.

      I hope that helps!

  2. I have 3 Indian runner ducks, 2 female one Male, they started laying an eggs day about a month ago (the females obviously), two days ago dotty just stopped laying.
    They live in a 50f x 50f enclosure with a small pond, fresh water bowls spread around and a wooden coop at ground level with fresh straw daily that I lock them in at dusk and let them out at dawn, they are fed on duck and goose mixed grain twice a day with mealwarm treats, once a day they are let out onto the main garden to forrage for about an hour or two. As far as we are aware nothing has changed but one just stopped laying eggs, she is active and seems healthy, Any advice please.

    1. Hi Mary,

      That was just two days ago? And she’s not broody? I’m not sure, but I would guess that she’s just taking a short break and will resume in a few days. My hybrid commercial layer chickens lay almost every single day, but occasionally one will take a break for a day or two.

      Do you think she could have chosen a hidden place to lay her eggs? Perhaps in the garden or somewhere outside of the enclosure, or in some hidden corner of their coop? A while back my chicken eggs dropped (I’m using chickens as an example because my ducks are Muscovies and Muscovies are not prolific layers like Indian Runners or these chickens), and it turned out that one of the hens had made a nest in the very back corner of our storage area, where almost no one ever goes.

      Beyond that, I’m not sure. It’s possible that this is the first sign of some sickness, but it’s unlikely. Most likely, she’s either taking a break or laying somewhere you don’t know.

      Hope that helps!

      Hannah Miller

  3. Hi Hanna,
    Thanks for your reply, not sure if she is broody as never kept ducks before tbh, but she is not keeping to the nest she makes in the straw she is out with the other ducks.
    Yes she has only not played for two days now but I got home tonight to find spots of blood in and around the coop, not a lot just maybe a dozen or so spots, I have checked them all for wounds but none seem to be injured, they are all as active as normal, the one not laying did a nice solid poo while I was looking at her and she didn’t look like she was straining or anything (I read something about egg bound ducks), at this stage i will just have to wait and see what happens tomorrow, I hope I am just being a “mother hen” over anxious first time mother, will keep you updated xxx

  4. I have 2 Indian Runners that are 2 years old (I got them Feb 2017). They live with a 1 1/2 yr old female goose and next door to them in the run lives 5 chickens. They have never had a problem with laying previously. They went into their usual moult in Feb (we live in Australia) and have not laid since then. Last year they went back to laying 1 per 2 days as the days were getting shorter. Would it be the crazy weather we have been having that has hampered their return to laying? – one minute its like summer, then next its winter! or a change in feed, my son recently brought the wrong bag of feed. Thanks for your advice

    1. Hi Suzanne,

      Yes, the feed change and the weather could certainly be factors. I’ve noticed that frequent weather changes can really mess up my ducks’ laying.

      What type of feed is it? If it isn’t specifically for laying birds, it’s possible they need extra calcium. Even if it is laying feed, they may still need a calcium supplement in order to lay well.

      You’re also approaching winter, so maybe they think the days are too short already. Most ducks molt right before winter and then lay again in spring. February seems a bit early to molt to me, but I’m not really familiar with weather in Australia. Or maybe they actually haven’t finished molting? Molting can sometimes be dragged out over more than a month, especially if the diet isn’t high enough in protein.

      Also, most Runners lay extremely well–but mainly just for the first few years. Breeds that lay a lot, won’t lay for long. They slow down much faster. However, I think they’re still a bit young to show any major decrease in egg production.

      Some of the other factors in the list in my article could be possible as well. Do you think worms could be a possibility? Worms can prevent or decrease laying. Some people deworm their flock regularly.

      It’s hard to say for sure, but I do think the weather is one of the most likely factors, and possibly the feed too. You might consider trying to counteract the effect by adding artificial light in their coop. Many flock raisers use artificial light in order to trick their birds into thinking the days are longer than they are.

      Hope that helps!

      1. Hi, I have 8 ducks in total. 3 juvenile females two of which have been laying every day and 5 x 2 month old ducklings, one of which is definitely a male. Last week my 8 month old laying Buff Orpington started to go broody. The eggs she was laying can’t possibly be fertile as the only male duck I have is only 2 months old. So I’ve been collecting the eggs on a daily basis, gently encouraging her to go outside and locking the coop door behind her so that she stays outside all day. I’ve also been fluffing up her bedding and basically destroying her nest. Well the last five days she hasn’t laid an egg at all and also the other laying duck has also now gone broody. The two of them just want to cuddle up in their house all day!
        What is happening?

        1. Hi Dee,

          That sounds normal. Not all ducks like to go broody, but those that do will lay a clutch, go broody on it, and then stop laying. They can’t lay while they’re incubating! In this case, you’ve stopped her from being broody, but she still stopped laying because she finished her clutch. She’ll probably start laying again soon, after her hormones return to normal. My Muscovies, which don’t lay very much, usually will lay a clutch of 5-15 eggs, and then stop laying and go broody. After I break up their broodiness, it’s usually a few weeks before they lay again. Since Buff Orpingtons usually lay a bit more than Muscovies do, I think she would probably start laying a little sooner than “a few weeks,” but I’ve never had Buff Orpingtons, so I can’t say for sure.

          As for the other duck, I’ve heard that broodiness is contagious. One broody lady will trigger everyone else to go broody. Either that, or they both went broody just because it’s spring and it’s breeding season and they think it’s time to make babies. They can’t tell whether their eggs are fertile or not. The other duck will probably stop laying soon too. And I wouldn’t be surprised if the third young duck will decide to go broody and then stop laying, too.

          Broodiness can be annoying for us egg-hungry owners, but it’s just part of owning ducks (except for breeds like Khaki Campbells that rarely go broody). They WILL start laying again, once they get over their broodiness and their hormones return to normal. Hope that helps!

  5. I have a Pekin who is 3 years old. She is quite attached to my other duck who is a male khaki Campbell. I have had them both since the day they hatched and they refuse to be separated. She was born with slipped tendons in both her knees but I take her to the vets on a regular basis to be sure she’s not in pain. She is on a basic pain killer which I give to her every few days as when she was on it regularly she wouldn’t eat, and then my boy wouldn’t either. They live on the Gold Coast in QLD, Australia. It gets quite warm here but they have shade and a small pool. She used to lay quite regularly but I haven’t had an egg from her in ages. She lives mostly off peas but I give her meal worms and grit as much as possible. Even cooked chicken which I found weird but my vet suggested. She is not super active but she never really has been. She swims occasionally and I put her in my large pool on a weekly basis to give her some activity. She has been moulting for AGES and I don’t know why it hasn’t stopped. My boy is not rough with her either. They only mate when I put them in my swimming pool and I usually stop them If he is getting too aggressive. I know there are lots of factors involved here. Not really sure what to do.

    1. Hi Stevie-lee,

      She’s not laying for the same reason she can’t finish molting. I’m guessing it’s a diet problem. Peas and mealworms alone are not a diet for a duck any more than peas and bacon would be for a human. Peas are fantastic, but only when balanced with other foods. Cooked chicken and mealworms are great too, but not by themselves. I would suggest feeding her either chicken layer feed with added niacin, or waterfowl feed if you can find it. You can still add peas, mealworms, chicken, and other veggies and foods, but they can’t be a staple by themselves. I once tried feeding my ducks only wheat, and I had problems with elongated molting for adults and stunted growth in babies. One type of food never comprises a full diet. Also, she needs calcium in order to lay.

      Beyond diet, there could be other factors. I’m not a vet or experienced with drugs, but I also wonder if being on painkillers for so long could be damaging her health and messing up her system. I can’t say for sure though.

      Can she walk? Lack of activity could result in obesity, and not being able to walk could also be stressful. In general, living with a disability could be stressful even without pain.

      Have you actually tried to fix the slipped tendon? Here’s a link about slipped tendons in case it has any useful or new information for you:

      So definitely change her diet. You might not see improvement immediately, especially since I think you’d be approaching winter in Australia, right? But hopefully she’d start laying again come spring. If not, then perhaps either her disability or the painkillers are somehow affecting her laying.

      Hope that helps!

  6. Hi, I’ve got 4 female Aylesbury ducks that I’ve had since they were 2 days old. They are coming up to a year old in a few days. 3 of my girls have laid an egg every day since October but one of my girls has never laid an egg at all. Any advice you could give me? She’s a bit smaller then the others but she seems happy and healthy. Always eating and drinking. I read about changing their diets but if the other 3 are laying fine could it even be their diet that’s the problem?

    1. Hi Michelle,

      That’s interesting. I’m not really sure. Are you absolutely positive the duck is a female? Assuming so, I wonder if it could be a genetic problem, possibly caused by inbreeding? I once bought eleven ducklings. At first, they all seemed fine, but then I noticed that one wasn’t growing as fast. The other ten were healthy and the females all laid wonderfully, but this one duck stayed small. As far as I knew, she never laid a single egg. I remember her feathers were also kind of weird. Other than that, though, she seemed fine.

      Some kind of health problem would be my best guess, but I don’t know for sure. Maybe she’s just a little weaker, which made her more susceptible to parasites, which hindered her from laying. You could try deworming them, just in case. Many other health problems can hinder laying, even if they don’t have many other external symptoms.

      It’s also possible the diet is fine for the other ducks, but not for this one. Ducks can have special dietary needs and sensitivities, just like humans. You might try changing their diet anyway, just in case. I would especially consider increasing protein and calcium.

      I’m sorry I can’t help more!

      Hannah Miller

      1. Thanks for getting back to me. I’ll have a look into changing their diets. I’m not fussed if she never lays an egg just curious as to why the other 3 do but not here.
        She looks exactly like the others has more energy too just a tiny bit smaller then the others but she always has been. Very cheeky girl too lol
        Thanks a lot 😊

        1. I have 2 khaki and 2 Pekin, there is one who is laying rubber eggs and the others only lay maybe twice a week. This has been going on for a few months now. They share a coop with chicken but have a fence in between them. The side that my ducks are on is about 4×6. Could this have something to do with them not laying regular?

          1. Hi Sherry,

            That would be 24 square feet for four ducks, right? Is this their night pen only, or do they spend all their time in this area? If it’s just for the night, it should be fine, but it’s a bit too small for a full time enclosure. The rule of thumb is 4-5 square feet per duck for the night, and at least 10 square feet per duck for the day or for a full time pen. I’m not sure how much a small pen would hinder laying, though.

            What exactly do you mean by rubber eggs? She’s laying eggs with soft shells? If so, diet could be the problem. They would need more calcium, and maybe more protein as well.

            Can you rule out any other possible causes of low laying, like parasites or predators?

            Let me know if you have any other questions!

            Hannah Miller

          1. Hi Sherry,

            It should work as long as it doesn’t contain anything from pressure treated wood. Mulch retains water well, though, and ducks are good at making a mess with their water, so it’s possible it could become muddy and yucky. You could also consider sand.


  7. I have five ducks (4 Welsh Harlequins and a Cayuga) nearly 1 year old who have been laying consistently for almost 6 months. We did get a few small eggs over the past couple of months but I chalked it up to their youth. Now we have not found a single egg for days. They are in a good sized paddock with cattle panel fencing to free range during the day (they also get some layer feed)and locked in an old horse stall w/ chicken wire around the edges at night. They don’t appear to be molting or ill. I can only think it’s a thief – a determined possum or raccoon could possibly climb in from the top. We did find a small snake a few weeks ago – not sure what he thought he was going to do w/ that egg as it was waaayyy too big for him & snakes seem an unlikely culprit for every single egg. No evidence of rats in the barn. I guess w/o a camera it would be hard to know but need to solve this soon!

    1. Hi JD,

      I don’t know what’s causing this, but here are a few more ideas.
      Has anything changed recently? Their feed? Their schedule? Has anything stressful happened?
      What kind of weather have you had?
      Maybe you could try arriving earlier to let them out of the stall? If you only arrive at 8 AM or something, there will have been plenty of time for a predator to take the eggs. Or what if they are hiding the eggs in the paddock where they free range? In that case, it might work to let them out later.
      I think a camera is a good idea, if you can find a way to easily do it. I agree that a thief seems like one of the most likely possibilities. Once an animal finds a source of food, they will usually keep coming back. Raccoons can get into almost anything.

      I hope you find an answer soon! I know how frustrating these issues are!

  8. Hi, I have a problem for which I would like some advice. I have a flock of parent stock which are a year old. They initially started to lay in December 2018 and the percentage laid rose up to 75% then we had a dip and problems – the egg percentages dived, I had lame ducks, paralysed ducks and some even died. I eventually isolated the problem as being low phosphorus in the diet. With the help of the supplier I tried to correct the problem remedially but this was not working as the males were having access to the females and mounting them – once they mounted them their weight would damage their backs. I decided to separate the males and the females and re-feed developer diet with the requisite Phosphorus levels for 2 months before rejoining the females. We have executed the programme and the females are now all fine, no sudden deaths have occurred. 17 days ago we changed the feed back to layer feed. Whilst the ducks were on developer the eggs being laid dropped to 7%. I now want to restore the previous levels, after 17 days there has been some molting, secondly we had a lighting problem with heavy rain that knocked out the floodlighting in the park. Right now I have 3 inherent issues 1. The birds are molting, 2. The messing up with the lighting (this has been repaired, but it took a while) 3. Stress caused by separating the females from the males. With this assessment do you think that if all the issues are resolved that normal laying levels can be resumed. Thanks Lewis

    1. Hi Lewis,

      Yes, I think that laying will resume once they finish molting, now that everything else seems to have been resolved. I don’t see any reason why they wouldn’t (although of course I could be wrong). Be sure that they also have plentiful access to calcium supplements.

      To avoid issues of males overmating the females and damaging their backs, I would recommend a ratio of one male per at least six females.

      It’s great that you were able to find the problem with the phosphorus! I hope you have success after this is all over!

  9. Hi,
    We have a Muscovy that lives in our yard and has babies in our secret garden every year. This year we locked them in the secret garden after they hatched and they all survived. They are about 4 months now, and we’ve released them back onto the river in our back yard. We still feed them every day, and they stay near our back gate. I have to assume the mom is laying eggs and the babies will some day too. Should I leave a laying box out? How can I capture these eggs?

    1. Hi Joyce,

      The mom isn’t necessarily laying. It takes several months for them to get back into laying after having babies. The babies will start laying at approximately six months of age, assuming it isn’t too cold and late in the year by then (it depends on where you live). They will lay somewhere in the vicinity of their home, so it will probably be somewhere nearby. Putting a nest box out near where they like to stay would certainly encourage them to lay there, although it wouldn’t guarantee it. Muscovies like to choose very hidden nests and are picky about where they lay, usually. Even the best nest boxes might not always appeal to a particular duck. But it might help.

      Hope that helps!

  10. How do you tell if a duck is too fat? Your article has given me some good suggestions for why my 2 one year old runners stopped laying a couple of months ago. 1) they did moult, but that seems to have been over a couple of weeks. 2) we introduced 4 new 12 week olds about a week before they stopped laying 3) they have food available 24×7 but their duck pellets are mixed 60:40 with wheat, and twice a day they get treats of fruit and veg, they have a huge pen with loads of foraging.
    So, it could be they’ll start soon because the stress of moulting and meeting the new girls is over, or it could be they’re fat, or it could be there’s not enough protein in their diet (although there are lots of bugs etc about just now). Any thoughts of where to start?

    1. Hi Christine,

      They finished molting a few weeks ago? Molting definitely has a huge effect on their laying and it can take time for them to kick back in after molting, so that could easily be the cause, although I would expect them to return to laying very soon if so.

      The stress from introducing the new ducks could have had an affect, but if that was a few months ago, that shouldn’t be making a difference anymore.

      The diet, though, could have an effect. It sounds like a pretty healthy diet, but not one that would maintain top egg production. Wheat is about 12% protein, and the ideal percentage for laying is about 17%. The veggies and fruit are very low in protein, so they would probably lower the ducks’ average protein consumption. And foraging, well, it’s hard to say, but a good chunk of that is veggies too. Unfortunately, constant laying is unnatural and thus can only be maintained with an unnatural diet. Foraging, veggies, and wheat are all healthy and natural, but they also make the ducks lay a more natural amount. If you want to feed them this way, that’s great (that’s what I do, too), but you might not get quite as many eggs as someone who feeds exclusively commercial feed. It can also prolong molting. I remember experimenting with feeding my ducks nothing but wheat (plus forage and veggies) a few years ago. The adults did okay, and they were Muscovies, so they didn’t lay a tremendous amount anyway, but they took forever to molt.

      As for being fat, actually, I don’t know of any reliable way to feel them or look at them and tell for sure whether they’re fat or not. Obesity in ducks hasn’t been researched or studied. You might try weighing them and see if they weigh as much as Runners are usually supposed to weigh. If your Runners have plenty of energy and do a lot of running around, and they still have their slender bowling pin shape, you’re probably good. I don’t think you have much to worry about. Runners aren’t prone to getting fat.

      Metzer Farms has some insights:

      I agree that feeding once or twice a day is probably better, especially since they have access to forage.

      Anyway, if you don’t think anything else in the article could be the problem (predators, hiding the eggs, etc.), then I’m guessing that the lower protein diet has just elongated the molting and is making them take a little longer to get back to normal. If they don’t start laying pretty soon, though, you might want to experiment with changing their diet.

      Hope that helps!

      1. Thanks Hannah

        That’s all very reassuring. They seem happy and active, and aren’t actually eating much in the way of pellets and wheat at the moment – it’s prime bug season here! The new girls are just coming up to 20 weeks old so I think I’ll see what happens in another month or so when they’ll be due to start laying.

        Thanks for your information and suggestions, very helpful.

        Kind regards
