Hey everyone I rehomed a cockatiel about a month ago, she was 9 months when I got her. She is happy to come out of her cage and takes herself back in when she wants to. Thing is she is absolutely terrified of hands, if you put your hand too close she will start hissing at it and backs away. I have tried putting gloves on but it doesn’t make any difference. She is fine if you put your head right up close to her it’s just hands. What should I do? Is it normal for her to still be scared of my hands?
