I have a couple chickens that have coryza...I think. Of all the diseases I researched, coryza seems to be the most likely problem. In these two cases, their eyes have swollen up, and when I drain them, I get this smelly, grayish pus with little white chunks in it . I'm putting Sulmet in their water, and they seem to be getting better. I clean their eyes up every day to make sure there isn't any pus build-up, but with one of them, her eyes look like they are sealing up a little more each day. It's like an open wound that slowly closes up. At this point, her eyes are little slits that she can barely see through. Has anyone ever heard of this happening?!?! I'm afraid they are going to completely seal shut! I don't know if that would cause the infection to get worse, or if she would just be blind, but either way, I don't see a happy outcome. What do I need to do???
