My mother contacted a good friend whose raised chickens for forever and he confirmed she has wry neck. She's eating and drinking but he says she's most likely not going to pull through. Thank you for all of your help guys and I'll keep everything updated
You mention that her her bottom jaw is swollen - can you get photos of that? Swelling of the jaw, I don't associate with Wry Neck, but the other symptoms you describe I do.
Wry Neck is a symptom - it can be caused by trauma/injury to head, vitamin deficiency, genetics and disease like Marek's.
I'm sorry that she is not doing well

Give her 400IU Vitamin E daily along with 1/4 tablet B-Complex. You can find vitamins at places like Walmart or CVS. Keep her hydrated and do your best to get her to eat her chick starter. You can also give her a little egg that may interest her.
Please do keep us updated.
