How are her feet screwed up? If you can, a picture might be helpful. If she can still walk alright, there shouldn't be a problem.
As for her eye, it's definitely better to keep her isolated until she heals. The other chickens will be pecking at her scab and making it worse if you put her back right away. If it gets infected, don't use regular antibiotic ointment (It is usually petrolatum based that will and can cause secondary infection) - Terramycin eye ointment should work though, it can typically be found at a feed store. As long as there is no infection, your girl should do just fine and will be back in the coop in no time. If an infection gets very bad or she starts acting weird, it would be wise to take her to the vet because she might have brain damage.
One of my boys lost an eye during winter (he was about 8 months old) and nowadays he's still doing fine. As long as they're isolated until they're back to health, life with only one eye should be just as difficult as life with two eyes, lol. I hope I was somewhat helpful, good luck!
