I have a ringneck pheasant in my room. He’s lived in here for almost 2 years. For the past seven months I’ve had a chicken living indoors as well because she became limp. After a few months he moved into her bin, and he goes back-and-forth from his to hers. Last week I noticed one of his eyelids taking on a white color, but I could see nothing out of the norm besides that. I look at him today and he has this big growth on the top of one eyelid, and then his forehead looks lumpy and swollen. I circled the lump on a picture below. Does only one know what this is and how to fix it?
