it is his abdomen. A large portion of it looks cover with scab. It is not wet or weeping. Beer belly would describe it's appearance. Feathers have stopped growing on that portion. I first noticed it about six weeks ago. I didn't think he would last this long but I began making sure he has veggies every day and feeding walnuts which are supposed to help with tumors in people. He has improved activity and is eating well and does appear to have gotten better. He still eats seeds but I only give a little every day. He does eat the veggies, pellets not so much, but some when the seeds are gone. The iodine/trace mineral supplement had a cool instruction to mix with a gallon of water , keep refrigerated to insure proper dilution.
Thanks. I had a budgie with internal tumor and limp leg, lasted about a month. When I saw this I immediately thought tumor, but when he started getting better I thought otherwise and the information you gave me is what I was looking for . He doesn't peck or damage the area. I'll try and get him on pellet only. Thanks !
