Hi everyone. I just adopted a pigeon (a texan I was told) from someone who could no longer have animals. He is eating and drinking fine but he has what I'm going to call a growth on the side of his mouth(the corner) and always has some yellow slimy build up on the inside of his mouth near the growth. When I clean it out it looks raw and sometimes bleeds. I use a q-tip and water, nothing harsh, and am very gentle. The person said it was maybe a vitamin deficiency but never resolved. I was told to just clean it out. I'm not sure if that's the case but I would like to know if there is anything I can do to help him. Thanks in advance.
