My hen, 12 months, was attacked about a week ago by the rest of the flock. Recently she has shown more serious signs and one of them being unresponsive. Right now we have a food and water bowl in front of her and we have tried to get her attention but she acts as if she doesn't hear or notice us. Earlier we had a banana in front of her and she would bumble around pecking the ground occasionally finding the banana to eat it. Is there a possibility she could be blind or deaf?
