I don't think it was being stepped on by another hen, or an injury or egg binding. Sounds like pneumonia, do watch you other birds carefully.
However, what I really think it might be, is a genetic problem. Sometimes there is an organ that is malformed, and while it can keep up when the chick is small, the bird out grows it, and then dies.
Chickens often are not real long lived.
