Did the raccoon get in at night, and is your coop and run secure now? It does sound like she has wry neck, also called torticolis or crook neck. It is a symptom of several possible problems, but in her case, it is likely neurological from her attack and head or neck injury. Giving her a small amount of scrambled or boiled egg for selenium, human vitamin E 400 IU, and a 1/4 to 1/2 tablet of human B complex daily is a good treatment for a few weeks. Walmart Spring Vally brand vitamins or Equate is inexpensive. Is she able to get enough food and water? Can you post a picture of her eye? Is it swollen shut or can you open it enough to see if the eyeball is intact? I would irrigate or flush the eye with saline solution and apply a bit of Terramycin or Neosporin ointment into the eye twice a day to prevent infection.
