So tonight is my girls first night in their coop with their run attached. They seem to love it but tonight I just went to check on them and they were all snuggled up outside in the run in the corner. They have already been in and out of the coop so I know they know how to get in. I put them in the coop so they could be warmer and snuggle up since it’s dark but they immediately all came back out. So I tried again, but they still came back out. How do I get them to go inside for the night? TIA!
