Any idea to why my healthy silkie would go blind. I've raised her since she was 2 days old. I took her to vet because she was acting weird (not coming out of coop and running to me like she normally did and just laying low). The vet diagnosis is she is blind. She is blind and under weight now since she is not eating as much. I've been bringing her in when I get home in the evenings to make sure she is eating and drinking she is also getting scratch, mealworms and I gave her a little bread last night. I just don't understand how this happened. I can understand being born blind but this I don't get. Any ideas? My other ladies are leaving her alone at the moment so I am letting her be with her flock. They are in an enclosed run when I am working and they get let out when I get home and its daylight so I am not worried about predators. She recently came out to explore with the others so I know she is feeling better some. I just watch her to make sure she goes with the other chickens. Thank you in advance for suggestions on how this happened.
