I have been out of town since before Christmas. My husband has been taking care of the animals along with our neighbors. I went to check chickens when I got home only to find one dead in the coup and others with weird looking eyes. It's like they are almost closed. I don't expect one of the affected chickens to last through the night. It just stands in the corner. They are year and a half orpingtons. We feed our layers the layer pellets. The have access to clean water at all times. I'm sorry I can't post pics now, in the middle of switching computers. That is the only visible sign that I see, the eyes looking weird, almost like a bump above them and almost closed. All of the chickens are not like that, only a two that I saw. It is now dark here and I can't see very well out there even with a flashlight. Please help.
