Chicken becoming blind - what to do?

[BlueMoon]

I think one of my juvenile Wyandottes has gone blind. She walks into walls, can't find food or water easily and her pupils are enormous.
She has always walked around with another chicken, almost tailgating her, but this one has found a new friend and the one gone blind is quite helpless without her. Point being I think her vision has been bad for awhile and without her guardian, she's doing poorly.
Is blindness common in Wyandottes? If she is a hen and we decide not to cull her, she'll probably have to live caged as she's now terrified of the other chickens.
If we do kill her, is there a reason we shouldn't eat her (other than I'm getting attached)?
Thanks - I'm new to the chicken world and appreciate all suggestions and comments

I think it's Southern28Chick who has a little blind chicken? She may be able to give you some pointers. Try looking her up here on the board.

Good luck with your hen.

Thank you . I did email her and she sent me the link how they made another coop for the hen.
I have 96 chickens of various sizes, ages and breeds. Building another coop, or even making an addition is not feasible in this situation nor this climate.
So the real question now is if I can't find her a new home, can she be eaten or could the blindness be indicative of a more serious problem that would either infect the rest of my flock or humans (even if cooked)?

Hm... again, I don't know the answer, myself, but dlunicorn might be able to answer that one. She's incredibly knowledgeable.

(I wish I could give you an answer!)
