I'm building my first coop ever and I'm loving the ideas on here. Once question I do have (along with the many more I will probably think of after posting this) is, do I need to physically put my chickens inside their coop at night or will they go in there by themselves when they're ready? Also do I need to shut the coop door. The run attached to the coop is secured and there are no openings for anything to get in there easily. They'd have to do some chewing and digging to get in. if the coop is fully enclosed does it really matter? Thank you for your advice on this matter. My husband and I are really excited about our new project.
