Sick hen - prolapsed vent, but something else, too?

One of my white rocks, Teresa, prolapsed a few weeks ago. We treated her as we've read about on the board, (No layer ration, minimal sunlight, private quarters) and she seemed well on her way to recovery. Yesterday, I noticed she seemed lethargic and not "right" so I caught her up and checked her out. I noticed her crop seemed enlarged and firm, and the hen was very thin (very pronounced breast bone). We gave her a warm bath, and while I was drying her in a towel in my lap, I gave her some olive oil/and water and massaged her crop, which she seemed to enjoy.

I am just not sure what to do now. She seems to have lost her appetite, though she is drinking well and preening herself, and is somewhat interested in the random bugs in the stall. She is sometimes dozing, but keen and alert when she isn't dozing. Not terribly interested in either chick starter or layer ration, but she will peck at wet oatmeal.

I am at a loss and would like to help Teresa if I can. While not exactly a pet nor am I overly fond of her, I do want to give the best care possible for her to have a good life. I am open to any ideas.

Thanks

Normal to runny. Constantly dripping clear thin liquid from the vent

Warm epsom salt baths, prep H. Crop massage and massage of the abdominal area (checking for signs of eggs or their remains)

No vet, will treat by myself.
