I too have a blind hen named Helen. She was attacked by a hawk and sustained injuries to her eyes and head. I isolated her and treated her wounds. She survived but was completely blind. The flock go into a barn at night and roost in a stall. I made up a stall for Helen. I put her water in a big metal dog dish. Her food in a pie plate. She quickly learned where these were. During the day, I put her out with the rest of the flock in the same area. She loves to go under a bush, on sunny days, she feels the heat and lays out in the sun. She loves to take sand baths. I believe her hearing and other senses have developed to compensate for her eyes. She has nannied many baby chicks and guinea hens. They peep and she goes into the "come hither and get under my winds." She opens her wings and crouches down so they can all come under her. I never worry that a moody hen will peck a chick that isnt hers. She is such a sweet bird. When it is bedtime I call to her and she makes a low drawn out cluuuuuuuuuuuuk cluuuuuuuuuuuuuuuuk sound so I can find her. (My pasture is all grown up with trails from the birds.) I scoop her up and put her in her private stall. Just watch out for any hen that might pick on the blind one. I have a wonderful Amercauna roo that keeps the peace. He always keeps and EYE out for Helen. This was 3 years ago and she is going strong and seems very happy.. Best of luck to you and thanks for not killing her. Animals have a wonderful way of drawing on their strengths.
