I had ordered some hatchery chicks. I have 2 buff brahmas. Both were supposed to be hens. I think one is a roo. This isn't a problem. He has a larger comb and larger and darker feathers on his feet. I know they are supposed to mature slower than the others but will he still crow at the same time any other roo? He is turning 11 weeks old. And, if he starts to crow will it be as loud as my Dominique?
