She needs more timing to be manned. Everyday, gently play around with her feet, and chest. You don't have to use your hands, even a feather can work. Prove to her that you are no threat and that it is okay to be trusted. Looking into the birds eyes, she will tell you everything of how she feels. Only you can know this for yourself, no one else.

She will be agitated by this, some birds are; but over time she will stop the biting and footing. Just make sure that if she's the type to foot a lot, focus on her feet more with the touching. This will take time, it took around 2-3 weeks everyday for my redtail to settle down. Today he doesn't mind, but when he has his own moments to say "enough" that is when I respect his space and leave him alone from "petting" him. Even being present with your redtail everyday for hours can help. It just takes time and patience . And when the bird "bites" or foots" do not pull away, you will be showing fear to her, and that's just what she is looking for. Hope the suggestions that all of us are providing is helping you out .
