My inclination is to dispose of the bird but IT IS NOT SICK. No Canker in there or anything else for that matter. If it was a common illness of ANY kind i like to think i'm clued up enough to spot. Honestly, other than the swelling (primarily on Left side) the wee do is bang on so i'm reluctant to put it down without Knowing what is wrong with it. Going to the Vet is out of the question, i know more about doos than any of them around here.
