Tips needed on how to care for blind chicken

I posted here a few days ago about how my flock got halved by a predator and my struggle to keep one of my survivors alive until she heals. following the attack, I noticed one of my ladies was kinda lethargic. she's part of a batch of egg layers I had just gotten. Took her in and I noticed she's blind. not sure if it's since the attack or she was blind before and I didn't notice-doubt it, eyes are still there, but no light reflex. How do you teach them to eat? I've been manually feeding her or leaving a bowl of blended cat wet food that she eats herself, she just can't seem to be able to eat birb food, not for lack of trying. she seems healthy otherwise, just thin.
