I have a 9 week old chick I ended up letting mom hen raise. I have been trying to handle regularly. I had both momma hen and baby in a grow out brooder because she ended up getting off her remaining eggs early and lost one of her chicks (literally). I have been letting them out supervized and this week I have let them out fully. Over the past day or so I have noticed many roo behaviors. So we shall assume this is a boy. However all of the aggression is directed at ME. He's already trying to flog me and jump up at my legs. Pecks at my feet. Actually goes out of his way to get after me. Should I be worried? There are no other chicks, just him. Everyone seems fine with him--he just is not fine with me.
