The chicken is (we think) a male of about 10 weeks old. For the past few days he's had this nasty swollen eye and I'm not sure what to do or how to treat it. (Piper the Gold Roo) I'm very new to chickens, any advice would be greatly appreciated! Thank you! UPDATE: His feathers have gotten dirty and ratty looking lately while all of the other, healthy chickens are still clean and shiney. I guess this is a symptom...?
