Hi everyone, I have a flock of 10 (2 drakes). It includes one khaki campbell, 4 blue swedish, and 5 Cayugas. The drakes are both Blue swedish. Recently I have noticed some of the cayugas missing feathers on the back of their neck. I mean like I see patches of just skin. Is this just the Blue swedish drakes being particularly randy with those girls? Or should I be worried? We also have 3 hens and a rooster but they don't seem to be bothering the ducks. Does anyone know what the ratio of males to females should be for blue swedish? I thought the 4-5/drake would be ok, but I'm starting to wonder. I didn't think they'd "molt" that much in one area at once.
