I have 3 six mo old roosters, one of which crowed today for first time. He is the meanest, starting fights etc. He is the one I like the least. He will try to peck my hands, face, etc. Anything really. He will chase the kids(3 and 4 yr olds) but I stand my ground and make the girls do the same. Anyway, one of the others is really laid back, shy. Doesn't get I to fights too much, if at all. The middle will, he will challenge the meanest of the 3, almost constantly it seems. Lol my question is which one is the one I should keep?
