I have a blind chicken. She is only blind in one eye. She had gotten sick and when we checked to see what it was, she had digested half of her crop! She is such a sweetheart, but she has learned that when there is food, you have to get it! She is sick anymore, just blind in that eye! But, don't judge her by her eye, that has nothing to do with it. You said she is a sweetie so go by that! Hope This Helps!
I love my chickens!
