Well, unfortunately, she is probably blind in the left eye, and possibly the left. The left may have a cataract which she might see some light and dark or blurry objects. Eye disorders can be a result of ammonia odor from droppings and poor air circulation in the coop, vitamin A or E deficiency, eye injuries or peck wounds, infections, cataracts, exposure to avian encephalomyelitis or AE as a chick, and Mareks disease. A blind chicken would be best in a familiar setting with food and water near her. Other chickens may bully or pick on her. So sorry that you were sold a blind chicken.
