Hi, my cockatiel is tamed.. I think. She steps up when I put my finger close to her legs, but if I put my finger to her chest she bites me.. But She doesnt bite for me to get hurt, she like taps my finger with her beak. I tried to hand feed her but she just keeps 'biting' me and hisses at me. Can I get some help please? And can I still bond with her if I have a male budgie always with her?
