My girls will not roost! They started roosting on the nesting box. I made it so they could do that anymore. Then they started sleeping IN the nesting box. So I took the box out last night. This morning they were on the floor. The roost bar is higher than the nesting box. Ever since they were attacked by the raccoon, they don't roost. If i place them on the roost bar, they tendto stay on it at night, but they won't do it themselves. Any ideas?
