I lock my chickens up at night. When I let them out in the morning, one of my buffs, Tiffany, flies from the door to the end of the run (about 8 feet) and smashes into the hardware cloth. She falls to the ground, gets up, and walks away unharmed. I'm worried she'll hurt herself or another chicken. What can I do to stop her from doing this or prevent her from hurting herself or another chicken? I don't want to clip her wings.
