One of my hens has an eye that I can only describe as weepy. I noticed it a couple of days ago, and thought maybe someone here could give me some advice for a treatment. Attached are two photos of the eyes in question, and one of the "healthy" eye (though looking at the photo, maybe it's a little weepy, too?). She's been wiping the side of her face against her shoulder and the feathers there are somewhat yellow. None of my other chickens are having any trouble, and I'm certain that no one is picking on her. Is it possible that she has a cold? Thanks for any help.
