We have two black sex linked girls, about three months old. They have the feather pattern of female black sex linked chicks but one of them has a noticeably larger comb than the other one. In fact she has a much larger comb than any of the other chicks, and they're all the same age. I'll try to get some pictures. She is a bit larger than the other one but not terribly so. Is it possible for a black sex linked with the female feather pattern be male??? Anything I've read on them says the males have the barred feather pattern but I just want to be sure. No signs of crowing or anything like that yet. And she has rounded feathers like the other one.
