Hello I have two free ranging hens who only go into their run at night to sleep. In the morning one gets very worked up to go outside and has begun running her beak back and forth along the cage. It didn't seem to be an issue (no marks on her beak or damage to the coop) so I just let her, but this morning it seems that she gave herself a gash on the beak from doing it. It's not very deep but I'm worried if I don't stop her she could hurt herself a lot worse but I'm not sure how to begin curbing the behavior. Has anyone else had this issue? How should I stop it? I would get up earlier but I've seen her start doing this at around 4am and while I will certainly make the effort to let her out before she starts getting upset i'm worried about slipping up and her getting hurt because i slept in.
