Hi! I have a a female super african goose that has a very large lump on her chest- the size of a large grapefruit. She also has a small one on the right side of her face behind her bill about walnut sized. She's had them since she reached maturity. She's about 18 months old. The closest avian vet is 50+ miles and they do not see waterfowl. She eats very well, but has to live with my one legged chicken as her 8 siblings hog all the food. I've searched online and have seen a few pics of canada geese with the very same chest lump, but no info. please help!
