Hen with cloudy pupils / eyes

[kris13]

She, at first, only had one that looked this way, now both of them are, and she acts like she can't see / possibly blind. (It's dark now, but I will try to get pictures tomorrow morning.) She's not even a year old, so can rule out old age. Thoughts? Both eyes were fine probably a month to six weeks ago.

Is there any eye drainage or crust around the eyes? How is your coop ventilation? Ammonia fumes from droppings in a poorly ventilated coop can cause eye burns. Some common causes of blindness are eye injury, infections, vitamin deficiency, viruses such as AE and Mareks disease, and cataracts. Has there been any change in the eye color, or just cloudiness? Many blind chickens can get along fairly well in familiar surroundings where they can find the water and feeders. Sorry about your hen.

No drainage or crust, ventilation is very good. We did quarantine her for a bit, but since nothing changed for any of the other hens, we mixed her back in. No color change minus the cloudy/grayish center now. When my husband was in the coop earlier today, she was managing to eat / drink fine, when our girls went out later, they said she was having trouble (but they were trying to hand feed her a treat versus the "never moves location" food and water.)
