Everybody knows ducks lay one egg a day. If you exclaim excitedly, “My duck laid two eggs today!” you’ll probably get funny looks. They’ll tell you, no, ducks never lay two eggs in a day.

But they’d be wrong.

Once in a while, a duck owner will get one more egg than the amount of female ducks they have.

Can a duck really lay two eggs in one day?

Surprisingly, yes, ducks occasionally lay two eggs in a day.

It’s rare, but it does happen and it’s completely normal. It’s most common in young ducks whose hormones are still out of whack. In fact, some people have even gotten three eggs in one day. Most likely, however, these extra eggs won’t last long. Soon enough, her hormones will balance out and she will start laying normally, one egg per day. These extra eggs are often soft-shelled, because ducks rarely have enough resources to make two shells. I once had a young chicken, Bettina, who laid two soft-shelled eggs less than an hour apart, on her first time ever laying. Her sister Ingrid later laid two hard-shelled eggs in one day. I’ve also had a duck lay two eggs in a day on at least one occasion.

Normally this is just a one-time thing. However, occasionally, a duck will keep laying two hard-shelled eggs a day for long periods of time. If you have one of these “wonder ducks,” don’t worry about her. Enjoy the extra eggs for as long as she’ll give them to you!


    1. It’s okay. If your duck is laying two eggs a day, she probably just doesn’t have enough calcium to make two hard shells.

      Soft-shelled eggs CAN be a concern, if a duck is regularly laying one soft-shelled egg a day. In this case, it usually points to a nutritional deficiency. But in this case, don’t worry about it.

  1. I have a khaki Campbell x duck who is in a ru with her 10 ducklings who are almost 3 weeks old. Tonight I found 5 eggs in the next box. I put fresh hay in there daily and im pretty sure I put hay in yesterday, but 100% sure I put hay in the day before and there were no eggs.
    The duck and ducklings have been confined to the cage since the ducklings hatched. No other adult ducks can get in there. The eggs are not unhatched ones I know this as 1: I cleaned all unhatched eggs out and 2: I candled and these are obviously fresh eggs.

    I’ve never heard of a duck laying so soon after hatching ducklings (she is still caring for the ducklings as any normal duck would). It’s currently almost winter here and there is a light on 24/7 in the housing area of the run to provide heat for her 10 ducklings, however I’ve used this setup countless times before
    I don’t know her age or laying history as she was given to me by people who had been feeding her after a neighbour dumped them on his property and left them there with no food, shelter etc.
    it’s almost winter here so daylight hrs are quite short, however there is a light On in the housing to provide heat for the 10 ducklings. However I’ve used that setup countless times before and never ever had a duck go back into lay until the ducklings were at least 10-12 weeks old.
    I don’t understand how on earth she could have started laying so soon, much less lay 5 eggs in 2 days! But I am absolutely certain no other duck has access to the house and run she is in, which is a professionally build one and completely covered with small diameter netting and solid roof/walls etc.

    I’m baffled…any thoughts?

    1. Interesting. Is it possible that this was a prank by neighbors or family? I remember a few similar cases on BackyardChickens.com that turned out to have been a prank.

      If you’re sure it wasn’t a prank, I suspect it has something to do with the light being on 24/7 or the fact that this is a Khaki Campbell. Is this your first Khaki Campbell? And how long have you had her? This is just speculation since I don’t have real life experience with a light in my coop, but I wonder if the 24 hour light stressed her and caused her to lay earlier than normal, since she wasn’t used to having it before she came to you. I’ve read that having the light on all the time sometimes works out fine (as it seems to have, for you, in the past), especially if they’re used to it, but in other cases stresses the birds and causes laying problems.

      And maybe Khaki Campbells just tend to start laying earlier. I don’t know. I have a Muscovy who just started laying this week, even though her ducklings are only eight weeks old. Campbells are known for extremely high egg production and not so good mothering instincts anyway.

  2. How interesting! I bet when ducks or hen lay 2 eggs in one day the eggs are almost see-through because of having so little time to produce the egg. Have you seen this with a few different breeds of ducks, or one? I once had this happen with a Rhode Island red hen, but only once..

    1. Yes, the eggs tend to have very thin or nearly transparent shells, but sometimes they’re perfectly normal. I’ve never seen any of my ducks laying two eggs in a day, but it’s possible it has happened I didn’t realize it, since I can’t keep close track on who’s laying and who’s not. I do remember once when one of mine laid a soft-shelled egg around 5 PM, but I can’t remember whether she laid one in the morning or not.

      I’ve heard of various breeds laying two eggs a day.

  3. My young Khaki Campbell Girl laid two eggs two days in a row! She is the only female duck I have so I KNEW it happened, but when I googled I didn’t expect to find confirmation that this happens!

  4. My female Pekin just started laying 3 days ago. She was hatched the beginning of February 2018. She has been laying 2 eggs each morning. The eggs look totally different from each other.

  5. We have a 5 month old peking duck and she started laying eggs at 4 months. But in the 5th month she started laying 2 eggs a day. She is still laying 2 eggs a day. We only have 1 male and 1 female. In reading i find that this is normal. We are also amazed at how large these eggs are. We are running out of recipes to
    use all our eggs. Just greatful and amazed.

  6. My female Peking lays two hard shell every day and has been for the last couple months. It used to only be one. I had four ducks and and am down to two because of predators. It seems for the first time she is wanting to sit on her eggs but how do I keep them safe since she laid them outside their enclosed house??

    1. Hi Holly,

      I think the best option would probably be to fence in a yard or run for your ducks, or make a mobile run. If you’re having predator issues and are worried about her eggs being stolen, it sounds like you really need a better enclosure.

      If that’s not possible or practical in your situation, perhaps you can create a small fenced box, like a dog crate without a floor, to set over her while she’s broody, with enough space for her food and water. Still, once the ducklings hatch, they will be even more vulnerable to predators than an adult, so I would still recommend a fenced yard or run.

      Hope that helps!


  7. Our two Khaki Campbells are Ducky and Spike… Fairly sure from the behavior that Spike is a drake. Today is day 5 of our young Ducky’s egg-laying. I have been augmenting the crumbles with cracked oyster shells as a Calcium supplement.
    I have not noticed any soft shells, bit one egg is somewhat smaller than the other…
    Thanks to everyone for their post(s).

  8. Thanks for the reply… Our Khaki Campbell, Ducky is still laying 2 eggs most days with one egg slightly smaller than the other. .. I’ve charted her production… and so far, she’s now in to her 4th month of egg laying. I do provide supplemental cracked oyster shells *which she loves – her egg shells are firm, not at all soft… The additional calcium supplements their normal 28% protein game crumbles… They also get a generous supply of raw leafy green vegetables (freely offered by the local green grocer). These eggs are huge. Even the smaller egg is larger than a jumbo store-bought chicken egg. But the consistency is great for making fresh challah and pastries!

    Such spoiled suburban pet ducks!

    I honestly would NOT like her to lay more eggs per day than she now provides.. I worry that she won’t be able to maintain her weight.

    1. She’s been laying two eggs a day for four months? Wow! Are you absolutely sure you don’t have two females? If she really is laying two eggs a day, I’m sure she’ll wear out and switch to a more normal pace eventually.

      Laying ducks don’t really need 28% protein. Layer feed usually has 16-18% protein. I wonder if she’d lay more normally on a normal layer feed?
