hi I have a white chinese goose that has lived in my yard for years. last year she developed a growth under her bill; an exotic veterinarian found cancerous cells. since then the growth has gotten larger, but my goose (her name is Duck Duck) has been doing quite well. I brought her into the house for the winter because the vet says she is elderly and i did not think she would survive the cold. Over the last month or so, the area around here eyes has changed. I don't want to put her through the trauma of another vet visit if this is just a sign of age, or if it is not something treatable. i would appreciate if anyone can comment on these photos.
