I have a hen who's been in sick bay for about six weeks with a gimpy leg. For the last three, I've been opening her crate door and she hops out every day and roams the coop. She'll often be lying down when I go in but sometimes eating and I've even seen her in the nest box. She'll put a little weight on her bum leg which is definitely an improvement. A couple of times she's been in line to go out with the other chickens in the morning but I've shooed her back. How long this is going to take? I'm worried that it's just never going to heal. Anything I can do?
