For the past few days, our hen has just been lying there, and can't get herself up. She doesn't appear to be in any pain, looks alert, and can scoot herself around enough to reach her food and water if they are kept near her, but she can't get up. I suspect it might be rickets, since she has been inside for a while due to non-chicken-friendly local ordinances, but I'm not sure. We've started putting her outside each day, law or no law, but I can't leave her out all day anyway because it's hot and she starts panting really hard after a while. Dh has called around and apparently there are no vets around here who treat chickens, so we're on our own. I've started giving her a vitamin supplement. Is there anything else we can do for her? She's our 4yo's special pet hen.
