My chicks aren't quite 3 weeks old and I see my rooster and one of my pullets "battling", is this playful or one trying to dominate the other? I'm new to all this and was wondering when he knows he's a he and the rest are not? I just put them in the coop and out of the brooder (getting too big and smelly for the house!). Do you have to seperate the roo's from the pullets? I just don't want to wake to a dead chick in the morning or something. BTW I too have a baby monitor near my coop. We have a stray cat problem on my street along with Coons and other wildlife scavengers . . . the baby monitor was just a thought so we could be awaken if something happened.
