Hi everyone. I just started with a few chicks. They are Anerucana birds. I ordered 6 from Az to Oh. 2 died the first night because my husband didn't believe me that raccoons can squeeze there head or hands through the slats. So now he has boards over the opening and the rest are doing fine. I think I have 1 roo and 3 hens. When can I expect them to want to sleep in their nesting box.
