Cinnamon Queen blind overnight

[luvthebeach]

This is the 2nd hen in a year that has gone blind overnight. She won't eat or drink. We know she is over 4 years old, but don't know her exact age. Her eyes look fine. No cloudiness or damage. Is this an old age thing or something else?

Any pictures of the eyes? What do you feed? How is the ventilation and odor in the coop? Things that can affect sight in chickens are ammonia odors from droppings, vitamin A deficiency, cataracts, infections or injuries, and Mareks disease. I hope that she isn’t really blind, but maybe just having problems. Are you holding food and water up to her beak a few rimes a day? Wet chicken feed in a small bowl cleaned daily might be attractive to her to get more fluids into her.
