About a week ago one of my chickens was being really loud so I went outside to see who it was. When I got to the coop I saw that it was one of my gray chickens, but I also saw that she wouldn't open one of her eyes. Over the past few days, we've been washing her eye with saline solution and applying an ointment. She seemed perfectly fine and happy until a few days ago when we washed a piece of twig out of her eye. Now she wot eat or drink anything and just sits in a corner all day and I'm really worried about her. What should I do?!?
