That is a great point Miamor. It is best to get them to roost at night instead of sleeping in a corner or in their nesting boxes. It's especially important not to allow them to sleep in their nesting boxes because they will tend to poo in their nesting boxes. If you break the habit early then you will have less to worry about when they starting laying eggs.I felt the same way when I put my girls out at 6 weeks. They did fine, except the 3rd night our favorite got smooshed RIP Princess. They were huddling together in a crammed corner of the coop in between the nesting boxes and the inside wall of the coop ( i suppose) because when I went to let them out the next morning she was still there I felt terrible!! Looking to replace her with 2 more chicks soon. That night I physically placed the girls on the roosting bar so they knew to huddle there. They've been doing it ever since! Wish I had known! Good Luck!
