I have a barred rock rooster. He is 11 weeks old and isn't crowing. I have 2 hens of the same breed and see a signifiant difference. So I am positive he is a rooster(I also ordered him sexed) I have read on here of roosters crowing in the brooder at 5 weeks! What gives, is mine broken?! Do different breeds take longer to mature? I appreciate your help! Thanks!
