She is likely in shock, and that takes the appetite away for a while.
You could soak some rolled oats (not instant or flavored) in enough water to cover the oats plus about an inch, for an hour or two, and give her that. Even if she will just drink the water there will be some nutrients in it. This is an occasion I might also consider putting just a sprinkling of sugar in the water, for calories. But go with the oat water first. If she has a favorite treat, see if she will eat a little of that.
I think that after such a trauma, blood flow to the stomach is not at normal levels, so some loss of appetite is normal.
But making sure she is getting some kind of nutrition through fluids is important.
See if you can give her some lukewarm baths. That might help unmat the feathers over the other wound.
Praying for you all.
