We built an adorable coop with all the correct amendments for our chickens and so far, they are uninterested in going inside on their own. They hang out underneath the coop and on top of the coop at night. It has four open windows, a roosting pole and nesting boxes as well as plenty of room to walk around. At night, we've been able to pick them off the roof and place them inside. They stay there, but they have yet to go in on their own. Can anyone offer a suggestion?
