Any one with any info on how to treat this would be greatly appreciated. I have been giving him antibiotic in his water and using a hot compress, also peroxide and neosporin. He is eating but gurgles a bit and this thing has got some green puss on it. I was told by a feed store owner to try and pierce the swelling with a steralized needle and have done so, but it just bleeds. I don't know if he was attacked because he is in a secured cage, I suppose another Rooster could have gotten his head in the small wire opening, but none of my other pets show any sign of injury. I don't have the means to find a bird vet and we live way out in the country. I am afraid to perform frankenstein surgery on my pet because I am obviously not a trained pro. Any ideas on what I am dealing with. I even thought it could be a cist. If it's some sort of parasite or growth I don't suppose he can live like this. I just don't know what to do. I was hoping it would start going down, but it's so big and swollen. Any ideas?
