Yesterday I was talking to the chicks (oh boy ) and one of the RIR's hopped up on top of the waterer. This morning she was up on the roost when I went in to check them. Practically all of them were flapping around, getting a little air, scooting across the brooder. It's like when your baby takes her first step, you can't wait til it happens, but once it does, it's all over! What happens if one gets out and can't get back in? I guess I'll have to cover it with some netting for now!
