Little rosecomb cant stand on one leg for several days now. Other leg is fine. She CAN use bad one to prop herself up a bit and walking on toes if she must. I have her inside, small cage. I am pretty sure she injured it falling between roost bars in new Eglu Go. I can't find info to help diagnose her can u help? 1. How does a break feel, what do I look for? 2. Her knee looked swollen for a time, is that a sprain? 3. She can scratch her head w the foot but keeps it straight, weight plus bending it seems to be the issue. What does that indicate? 4. Cant find a tendon issue, would it be obvious? 5. B vitamins ACV and organic grain feed, mealworms, good appetite. She was always very delicate ball of fluff, scratched stuff backwards higher than any chicken I ever saw.
