I too have a special needs chicken. She didn't start out that way, but at about age 3 she started going blind. She is 5 now, and can't see much, but a little I think. SHe is an EE and never laid worth anything. She still gets on the top roost and when I enter the coop every morning she expects me to get her off of the roost and put her by the water and feed. She talks until I do. The others peck at her once in a while, but not really more than other chickens. She doesn't like to go outside the coop. The bright sunlight seems to bother her more. The roos tend to take advantage of her quite often because she can't see to get away.
