rescued cockatiel chronic scraping roof of mouth until bleeds with tallon
I rescued a male cockatiel about a month ago (I had one for 22 yrs befor it passed) is chronically scraping the roof of it's mouth with it's toe tallon & it draws some blood. I hear the dry scraping over & over. He is not happy and is otherwise healthy eating, drinking, plays with toys,sleepng,feathers look good, but is hostile to me and I am worried about the bleeding (not profuse but can cake on feathers on either side of mouth). My previous cockatiel which I raised from youth was very social & responsive so I am at a loss as to what to do about this issue! Help!
