I have a coturnix that has a swollen hock so bad that she is forced to walk on her hock because her lower leg is stiff and not usable. I have kept her separate cage and on shavings instead of wire so she doesn't have to move much to get food and water and so she can rest her legs. Her other hock is a tad bit swollen but she can still stand on it. Other than her leg issue she seems content and will even try to jump a little at times. Does anyone have any idea what is causing this and if so any suggestions for remedies so she doesn't have to spend the rest of her life in a cage by herself.
