We are going out of town on a Thursday and my son and his family can not come to house sit until Friday afternoon. This means no one will be home to lock up the hen house Thursday night. We forgot to close them up about a week ago and we either lucked out or the preditors have not yet discovered them. I do not want to leave them cooped up for 2 days. SO my only other oprion is to leave them in an open coop unless someone else has a better idea? We do not know our neighbors. So that is not an option. I do plan to leave the big door closed. We have it open now because of the heat.
