Here are some good books and websites about ducks. Some are about chickens as well, but most chicken information also applies to ducks.
Websites
Backyard Chickens: This is probably the largest poultry website there is. It’s a wonderful resource, and you can subscribe for free in order to post on the forum. It has information, coop designs, breed and product reviews, and a large forum. There even is a forum for ducks.
Muscovy Duck Central: A website dedicated to the Muscovy, with a forum, basic information, color types, nest box ideas, how to determine gender, and more.
Raising Ducks n’ More: This is my Youtube channel, where you can watch my ducks and see videos about raising ducks.
