When I first got a bird, Mesha(RIP baby boy!), he was abused so he wasn't tame at all!!! He would squak and bite us as well, what got him out was my sister's braces he loved the shine of it! He would crawl on her and talk to her braces! I think it took him about 1/2 year to come around to us. But like popcornbird said you should bring them out everyday or at the most sit with the cage door open and talk to them, that's what we did with Mesha
