Helllo. I read your post and I wanted to share my experience with you on this one. The first one I had like this was our last hatch the begining of October and we had one little fellow with a broke looking leg and he managed fairly well, I made sure he got his food and water several times a day and he than started to get it on his own. He lived a little over a week , he just scooted around on what he could use , I did not want to get shed of him just because of this and wanted to keep him so we were fixing his own little place to live when I noticed him gasping for air, the others , would sleep right beside him at night , I like to think they were trying to take care of him , but when it got a bit cooler in the brooder , they crowded him , he was unable to get out of the way and I think they killed him by smothering him. This hatch , we had one with the same thing ,but he is holding his own in there with the other 8. I am unsure what causes this, but I think that as long as the others are not bothering him , and he is eating and driniking , he should be fine. He sure is a cute thing, what breed is he?
