One of my 7 month old chickens started keeping her eye closed. I've been flushing the eye with salt water. She's having trouble eating from the regular feeder (depth perception problems) so I've been feeding her lentils and oats because she'll actually eat that. I'm making sure she's eating and drinking. She's much more sleepy than usual and stopped laying a few days ago but her posture is getting better. Anything else I can do for her or am I just keeping her comfortable before she dies?
