Ever since we got our tiels, the girl, Fancy has been so unapproachable. If we put a finger near the cage she lets out a big sqwual and then will bite if you keep your finger there. Do most Tiels to new homes do this?

Also .. what could it mean when they scream so loudly it almost hurts my ears!? I mean they everything they need in their cage .. so could it be they want out of the cage? But I don't know how that would work cause they wont' come near me .. lol
