My 27-month-old rooster, Bus, has yellow spots at the corners of his mouth and on the roof of his mouth. His throat and tongue look clear. If it is Canker what are my best treatment options? I've read on another thread about treating with Fishzole, but I'll have to order some, so what should I be doing in the meantime?

Sorry, not the greatest pic, but it's hard to get good lighting inside a rooster's mouth. Any advice will be greatly appreciated. We love him dearly. He's been blind in the swollen eye since he was about 5-weeks old...poor baby.
