one of my girls was caught in a bramble bush the other day, i could hear her when i parked up to go and check them which is about half a mile away, i thought she had got out and seperated from the flock, but she was probably eating the blackberries, pushed in too far and got tangled up, took me a few mins to cut the thick bramble that was wrapped around her. then she was good as gold. hate to think if no one was checking each day....
