ECBW, I'm pretty sure you should not feed starter to full grown hens. Here the new chicks will be introduced to the converted stall while the big girls are out free ranging. When they come back in @ night they will have the rest of the barn to mill around in, where their feed, water, and nesting boxes will be. The babies still have a few weeks worth of starter/grower left so let us know what works. The laundry room looks like a war zone.
