This is my first post and too soon for me to post pictures. I have two BO and I am afraid one may be a rooster. "He" was darker and bigger as a chick. Now at 7 weeks, he has a larger comb and wattle than the other. When I look at posts of older hens "he" looks like an older hen. Is it possible that one is just growing faster? He is still a bit darker than my other one.
