I am seeing some health problems and I am concerned that there could be an underlying issue I need to deal with. I have had birds develop difficulties walking or standing and one bird I observed this in actually died. I will try to describe the circumstances here: Starting with the most recent issue and going backwards from there - 1. The hocks on one of my birds have started to turn inward. This bird is now having some difficulties walking. 2. In the last month one of my birds sustained an injury which resulted in her not being able to even stand. I isolated her, built a support for her, and did some “physical therapy” with her so she might be able to recover. Over the next 3 weeks she did seem to mostly recover, but a few days after returning her to the flock (12 birds total) I found her hunched over and very weak. Unfortunately she then died in my hands when I picked her up to inspect and help her. 3. Over the past two years I have had occasion to have birds develop difficulties walking and sometimes even standing. In each of these cases I have been able to nurse them back to health but they do not always get all of their mobility back. My questions are: - is this anything you have heard of? - is it likely that my flock has a problem or illness? - is there anything I should do differently? For some background - I am raising my quail flock (12 birds) in my backyard and they are sort of as much pets to me as they are egg layers. I mention this because I am willing to go to some lengths to help even individual birds.
