I bought 3 ameraucana chicks (paid for pullets) in August from a hatchery and from pictures I have seen I now think 2 are roosters. They have very large plum tails with long feathers on their backs. The thing that is confusing me is they haven't started crowing at all and they do not have any spurs forming. One is getting kind of aggressive around my other hens. I just don't want a rooster because the last time I had one (RRI) it attacked my grandson and I just can't have that. Any ideas?
