My chickens are all acting like bad teenagers. They freerange during the day, and sleep shut up in a secure coop at night. Until recently, they have always put themselves up in the coop when it gets dark. Lately, the younger crowd(3.5-5m) has been hanging out outside, staying out late. Just now I went down to close everyone up, and had to herd them all inside so I could shut the doors. Before I even got back up to the house, I heard a giant commotion and ran back down. They had broken down the back door and were all outside again! One chick had gotten himself stuck in the door and was screeching his head off. I freed him and he seems ok. But now there are chickens everywhere!
