I need help! My chicken was attacked!

My ladies were out playing were they weren't suppose to be, and a lynx got one of my girls, and only injured my Americauna hen. I didn't see it happen, but there were a lot of feathers that came off of my Americauna, and she had a Little boo boo in her wing/arm pit. At first I thought she was just shaken up and would be better the next day, and she even wanted to sneak back out when I put her back in the pen! But the day after, (yesterday,) she's been acting like she's ill. She hasn't been moving much, she hasn't been eating or drinking water, she just sits with her head bowed and has been drooling slightly, and her left eye has been closed and wont open, and she has her other eye closed by choice mostly. We aren't sure what to do, we've given her some antibiotics through an eyedropper, and she wouldn't open her beak. She's been very weak, but can still move when she really wants to, and has been sitting in the egg house almost the whole time. She did lay a normal egg yesterday.
That's all I know right now! Does anyone know what I can do to save her? She's our favorite bird, and without her our last chicken will be alone and we would have to get rid of her. We can't afford any vet visits.
(I'm brand new here, just let me know if I posted this wrong or whatever.)

Honestly, I dont think there's much you can do. After the antibiotics really thats about it. Cats can have nastiness in their claws that can cause death through infection afterwards. I'd put her up away from everything else if you could (maybe a crate in the garage?) so no other chickens pick at it or flys lay eggs in the wound. There may be some kind of antibiotic spray you can get at the local farm store and try, but after that I dont know.

You'll know in several days. I've had them act like that and then end up dying a few days later, and I've had them get injured and then heal up just fine.

Good luck

I would try to feed her water. Otherwise you can't do much. If it's an infection she is likely to die if it is only an injury she is likely to survive.

Did your chicken survive?
