I have a two 2 month old chicks that are half black ameraucana and half black frizzled cochin. One of the chicks is smooth feathered and the other is frizzled. The smooth feathered chick is showing signs of being a rooster. It is much larger than it's sister, so big I can't even fit my hand around him like I can do with his sister. He has an enormous red comb compared to his sister's which is small and yellow. His leg feathers are much larger than the other's and his beard has already come in. Hi sister's beard is only halfway in. The only doubts I have are that his hackles aren't pointed and his saddle feathers aren't hanging, Does this change over time?
