I have what I think is 4 males and 1 female, ordered a run instead of getting the female or males. Any way, I have three black welsh duck and two gold stars hybrid, one of the gold stars are out casting one of the male black welsh and won't let the other go by him, if they do he goes after the one that is being out cast. also the gold star that is doing all this is also a male. I haven't been able to find anything on behaviors that is helping me. I do realize I need to get possibly more female or can they live with one female being a black welsh? and will she pair up with one of the black welsh or will she pair with any of the the male no matter what breed of duck they are?
