I am in the process of getting my first ducks. I have been researching breeds and decided on Cayuga, Khaki Campbell and possibly Rouen or Muscovy. I am only going to start off with two or three ducklings, more than likely I will go with a Cayuga and a Campbell. I have done lots of research on both breeds and they fit my requirements better than any other breed. I have a few questions still... Should I get the same sexes in both breeds? Does is matter if one is male and one is female? I wanted to get a male Cayuga and a female Campbell. Will they breed? This may sound dumb but, I don't want to cross breed them. I want to be able to eat the eggs, therefore I don't want the eggs to be fertile. Serious answers only please.
