Hello!! I have two khaki campbell drakes who seem pretty aggressive towards each other (always pulling at each other's feathers & one chasing the other around ... year round!). I am thinking that if I get 3 or 4 female ducks for them, things might be better. Someone in my town is selling female muscovies ... any experience out there with those two breeds together? Or know of a combo that I should definitely avoid? I'm looking for friendly ducks that my young children can interact with, for them to free range in our yard & garden, & smart enough to hide from foxes! Our current drakes seem to keep themselves under cover pretty well & we know there are foxes in our neighborhood. I haven't kept them safely locked up because I imagine their fighting would get all the more worse if they were bored. I'd like to keep them free-ranging. Thanks!!!
