Help!

Yesterday I stepped into my coop to see that a rooster I raised attacked one of my older hens. I’ve separated them both from the coop, and cleaned my hen as best I could but I feel like I could do some more to help her. Bother of her eyes are swollen, one almost completely shut, most of the feathers on her head have been plucked off from the rooster. I’ve used Vetericyn,and Blue Kote on her head and am continually cleaning the area. She’s taking water but hasn’t eaten much. Yesterday she laid on her side for a while, today she’s sitting up but still isn’t standing or walking i’m hoping she’ll be okay and isn’t suffering any serious injuries.

If any of you guys have any tips i could use that would be great! i’m a high schooler and can’t afford a vet let alone find a farm vet close enough for that matter.
