I've had this bird for almost 2 years and she's not warming up to me at all. I've tried hand feeding, she hisses at me all the time and is always staying in the cage or a place far away from me. She flys to me now and then and walks on my arm and chills on my shoulder sometimes. I just don't feel a bond with my bird and I feel like it hates me sometimes. I nearly fricking cried a few times. Does anybody have any suggestions?
