I have a 6 month old buff orpington rooster that until today has been a family pet. He would eat out of my children's hands and let them pet him. We slaughtered our heritage meat chickens recently, so he is now the only rooster on the property. My children (3 & 6 years old) were having races on the lawn and he came flying up and chased them. The six year old got away, but he landed on the younger one and scratched him before I could get over and knock him off. He continued to try to go after them even with me standing there, I had to send my boys inside. They were not running near any chickens (they were on the other side of the house) or even really loud, so he was not protecting his girls. I like letting him free range, but want my kids to be able to play. What should I do to try to get him to stop? Is it likely he will continue this behavior?
