I have a rooster that started limping 3 weeks ago. It came on acutely and is severe enough that he will toe-touch, but doesn't bear any weight on that leg. I couldn't find any external injuries then or now. I put him in a pen by himself to baby him, but he hasn't gotten any better. I took him in 2 days ago to have his leg x-rayed, which showed no reason for his limping. However, when I handled him I realized he has lost a LOT of weight...he's skin and bones! Now he doesn't even seem to have an appetite and just lays around and hardly tries to walk at all. I've been syringe feeding him and giving him pain meds, but he doesn't seem to want to make any improvement. Any ideas on how else to help him?
