My 5 ladies are only a week old, and very active when they're not eating, drinking, or napping so suddenly I worry that they've hurt themselves (so far, so good.) But I just moved them into a larger brooder because they seemed to need more room, and it looks like they're trying to fly. Is this normal? These are my first baby chicks, and I thought they'd be acting more like newborns, eating, sleeping, and pooping. I haven't put a roosting branch in yet because I thought it might be too early, but if they're attempting to take off across the brooder, should I put one up for my girls?
