Incubation/Brooder area for the mama so the other hens leave her alone. I've only had a broody raise mail order foster chicks but NOTHING messed with her babies and none ever got lost. Only took a couple of weeks with their own food and water before they were eating from the hanging feeder (I lowered it) and the waterer the older girls used. They were let out of the brooder area in the morning when I opened the barn. I think Zorra tired of waiting since one night when they were 2 weeks old she moved them to a nest box 2' off the ground (with an access bar at 18").
