Hi, our cockatiel is around 12 years old. In recent weeks we have noticed first a small dark lesion just to the right of his mandible. Thinking it was perhaps food i scraped it away and it bled for a short period. However this week there appeared one then two translucent pink lumps at the same site. Three days later the lumps are smaller and very dark: perhaps necrosing. The the back "corner" of the mandible also seems to be detached from the skin to an extent. Any ideas people? Thank you so much.
