The Call Duck is a bantam breed of domesticated duck raised primarily for decoration or as pets. You have to like the person who first breed a decorative duck.

Question by E. B: Raising ducks with chickens and roosters?
I’m planning to get chickens and possibly a rooster but I was wondering if ducks would get along with them. They will be egg layers and I will get them when they are chicks. Can you recommend a good duck breed for eggs? Thanks!
How big should the coop be? I planning to get 12 chickens and 2 or 3 ducks. Thanks!
