I am posting this thread not for response but to help others who's bird may have similar symptoms. Lovebird was an Isa Brown who was 4 years old and had stopped laying eggs a year ago. Looking back on the last couple weeks the cancer progressed like this. Two weeks ago I noticed she was loosing feathers and her wattles/comb looked a little pale. I assumed she was molting. Last week I noted she had a messy bum and was a little bloated ( like an egg bound hen but she quit laying a long time ago) and could no longer get up to the roost. Her walk was like a penguin. She was given soaks and mineral oil and vitamins. I felt what I thought was an egg in her ovary but the oviduct was empty. 5 days later the so called egg had doubled and Lovebird was alarmingly thin. She died the next night in a bed of straw. It was not pretty to see her deteriorate so fast. I had resolved to cull her the night before she died but she saved me that pain by expiring in her sleep.
Hope this helps someone else who may have a similar scenerio.
