Hen with neck problems after mink attack, please give advice!

A mink managed to get into my coop early in the morning about a week ago, and one of my hens got attacked. At first we thought it was just a small bite to the face, but she got worse over time and seems to have a bad case of wry neck, and maybe something else. I've been feeding her egg yolk and lots of electrolyte water, and while she seems awake and curious she can't manage to eat or drink on her own anymore, even when she seems to want to (misses the water and swallows like she drank anyway, or just swallows repeatedly next to the food instead of pecking it). She's constantly swallowing and smacking her beak, and I'm not sure how to help her any more than what I've been doing. It's been a week and she hasn't died yet, but I don't know if what I'm doing is helping her or just sustaining her as-is. Does anyone have any advice?
