Urgent- fox attack, injured hen

[SomeChookLover]

I came home today to find feathers everywhere. One of the hens to survive has a huge chunk taken out of her back and lots of feathers removed. She’s still walking and awake but I’m not sure how to treat her, and going to the vet isn’t an option. Any advice is greatly appreciated, thank you.

More info: a second hen has been found, she has one big gash on her back but had some water and a bug, currently sleeping in a hutch. The first hen has 3 main injuries on her back and sides, is still quite stressed and with the second hen. All their injuries have been treated with iodine.
