Until the coop was finished, we had our chicks inside. Now that they have full run of the fully-enclosed coop and run, they appear to be happy. However every night, they are crouched in the corner of the run, huddled together to keep warm. DH and I go out every evening and physically put them into their coop to sleep and they usually stay put unless it isn't fully dark yet. In the morning, they are out and about when I go out to check on them. How can I get them to go into their coop at night to sleep by themselves? I would think that they would want to go in there since they would feel safe, etc.????
