I'm sorry that you're having so much trouble. This link says that birds can get scabies:
http://www.cfsph.iastate.edu/FastFacts/ ... asis_F.pdf Scabies is caused by mites, and many mites are species specific, meaning that they only attack one kind of animal. So I would think that for your birds to get it from you, it would have to be a type of mite that bites both humans and birds. I don't know if there are any mites that do this.
