That's pretty infected. My guess would be there's no eye left in there. If there is any way, she should have some oral antibiotics. Barring that, I would try to clean out as much as possible from the area at least once a day. You can try a warm compress on the eye for 5 to 10 mins, or as long as she'll tolerate up to 10 mins. Run a washcloth or clean rag under the hot water faucet to a temp that is comfortable to your wrist, and hold it over the eye area. If you can get some terramycin, apply that after cleaning. Neosporin in a pinch. It's good news that she is eating better and is perkier. This could be a bit of a long haul, but things look hopeful.
