x2 I do the exact same thing.I always put our chicks straight out in the brooder that is located in one of our coops. It is big and predator safe, and has a heating pad if needed they can get to. This is of course chicks we hatch in the incubator. Our chicks hatched from mama hens, I never mess with, I just let the mama do her thing. It has worked so well and no mess inside to deal with everyday.
