I'm new to chickens, and my husban insisted on a Rooster. He thinks we have to have him to get eggs, I didn't correct him because I wanted a rooster so we could potentially hatch our own chicks one day. My DM keeps telling me I'll have to keep him seperate or he'll hurt my hens once he grows up. The thing is, he's a pretty sweet chick right now. He's going on a month and a half old, and he's not really mean or aggressive. He will occasionally flap his wings, or dole out a peck, but usually he's content to sit in my lap and be fed treats (or chick starter) from my hand. Do they normally act this way, and then turn mean?
