It is not definite yet, but I think I have 3 drakes and one duck. They are 7 week old campbells and I was planning on keeping them for eggs. I can hear one that quacks. The three other are quiet. I am still hoping that I am wrong. But if I am not, how many drakes should I keep? I hear that you aren't supposed to keep a pair as the male is quite aggressive to the female. And you can't just keep one duck by herself. Would it just be worse if I kept 2 males or would they spend half the time fighting each other and leaving the duck alone?
