Very interesting thread. I recently had a chicken with canker. Almost exact symptoms you describe, but no mass was apparent in the mouth or throat that I could see. Peter Brown with First State Vet Supply helped me find the metronidazole locally so I could treat her right away. He also taught me how to do tube feedings so she wouldn't die since she wasn't eating and drinking and had become very weak. Within three days of treatment with the metronidazole, she was almost completely better.
Remember, you can't always see the lesions of canker. They can be inside the crop, in the esophagus, even into the skull. My chicken was having a very hard time breathing, so I think her lesion was in the esophagus and pressing on the trachea.
I hope you find your answers soon.
