We usually have to tap to show her where the food is, or put her foot on it then she understands and tries to pick at it. She had a hard time finding the bread though. She is smart enough to try and come to me when I call her or if she is stuck and I am calling her she will cluck in answer so she can be rescued.
Every night the other chickens put themselves to bed in their little hen house and every night one of us goes out with a flash light to find Helen and put her in the feed bowl in the coop so she can find her food and be safe at night. The other chickens don't like her much but only one of them really picks on her.
I have no idea how she lost her sight, somebody showed up on my doorstep with her, she was wandering lost and alone in a field.
