Hello everybody! This is my first flock. I have three Brahmas, two Buffs and one Dark. Could somebody please tell me why their combs are so different? They are all from the same "litter" so to say, so they're all 22weeks. Is it just that Dark Brahmas' combs aren't as bright and red as the Buffs? Please don't tell me one's a rooster. I've already had to exchange one of my Brahmas because it was a rooster! I cant take it again. I haven't heard any "crows" yet!
