I Have a common mynah who has been acting strange. He has been pecking at his feet until they bleed. Today I found a LARGE (3/4") round ball in his cage. It looks like it has veins in it. Is that a dropping or throw up?
I am not a bird expert at all. I know one thing, it's not vomit as birds don't vomit the way you and I do. I would call a vet that specializes in birds. Birds get strange stones that can pass sometimes, and some of them are fatty type stones. So call a bird vet asap.
