Thank you for the replies to this thread. I have a mean one too. He is about 6 months old and getting worse. We were keeping him because DD liked him but now she is afraid - he chases her too. I know he picks on her because she is the smallest person in the yard even when there are other people outside. At this point she said as long as he is taken care of while she is at school and it is over when she gets home, she is OK with it. He also crows constantly and has an annoying pitched crow. We have a new hatch of 4 and if one of the chicks is a good rooster, he can replace "Dad". If not, I will do without a roo. What is a good way to separate the bad rooster from the flock?
