that for researching! did your hen recover quickly/at all?
She isn't ill but as far as I know she is still blind :/. I just finished my researching. I couldn't find any symptoms for bacterial infections in the eye except one thing. There is one disease, Conjunctivitis, that can cause blindness in the chickens eyes because of high ammonia in the bedding. It says that the eyes get cloudy, not specks though :/
