So that kind of confirms she was injured somehow. So I would continue treating those and see how she progresses. Daily soaks in warm epsom salts can help with pain and swelling, so that might help her leg/hip. If it's cold where you are make sure she's completely dry afterwards. You can use a blow drier on low.
For the eye, I would say to also keep an eye on that and see if it changes. It doesn't look exactly like what I've seen in my birds who've had occular Marek's, and it also doesn't look like the classic gray eye that most literature shows. But progression can be slow. The dark spot may be just spot of pigment in the iris, it happens sometimes. Do both eyes look the same, or different from each other? Does she seem to see OK and pupils react to light?
Below I will attach some examples of chicken slings, which if needed you can use for periods of time to let her rest more comfortably, eat, drink and poop. You do need to supervise so that she doesn't hurt herself trying to get out of it.
