Hi: My Ameraucana hen Hillary started making crowing noises a few days ago. She is 2 months old now and currently the boss of the other 11 hens (she doesn't know yet that the others will end up being double her weight ). I can't see much of a difference between her and the other hens and would really be surprised if she turned out to be a rooster. The only thing is that her comb is a bit redder than that of my other Ameraucana. Can it be that she is crowing to show off her dominance? If she is a rooster what do I need to look for? Thanks!
