I recently built a real rough temporary run on the side of my coop for my chickens to have some outdoor time in during the day due to my roosters loud mouth issues. I started letting them go out in it Monday and all of them were in the coop when I went out to feed at night Monday, Tuesday and tonight except for this girl The first night she was standing outside yelling at the coop frantic, then last night one of my silkie roosters was yelling out to her. Well tonight, I was a little bit late and I felt awful when I came home and she was sleeping all by herself in the middle of the run. It is pretty cold out and she was pretty pathetic out there. I couldn't figure out what the issue was and then it hit me she can't get back INTO the coop! There is about a one and a half foot high space between the ground and the door and all of the other chickens fly up to it. She can't fly! Tonight I stuck a long piece of wood out the coop door, she walked right up it and into the coop! Crazy chickens!
