We have polish chickens about 6 weeks old. We put 3 of them in the coop with our year old chickens & 9 week olds Polish. They were going in at night and all was well. Then tonight I went to make sure they went in (we have an automatic door and I check every night to make sure they go in) I noticed our one baby isn’t anywhere to be found. Possibilities she will come back in the morning? She is my sons favorite chicken I feel terrible. I didn’t think she would escape as shes been in the coop/fenced area for a week now. Thanks. Kind of new to this
