I take good care of my chickens, and I enjoy raising them. Now, I have 70 chickens, but now after four years of breeding, I have more roosters than hens! I don't know what to do. I've tried giving them away to good homes, but no one really wants roosters. And then they all started killing hens, starting with my little silkie hen and my old Buff Orp. I seperated the bad roosters from the hens, and even went to the extreme of leaving them out all night, but nothing has happened to them. The only rooster that has been killed by predetors was one of the gentle ones that I wanted to keep. And, even worse, out of the twenty five chicks that hatched this year, six of them have started crowing! What can I do to fix this problem?
