I've had three females and one male and I have one of each right now (Zoey and Sweetpea) and they were/are all different. One of the females, Cowboy, did not like to be touched at all - she wasn't aggressive at all but she was not 'into' people. Tobita was the most affectionate bird I've ever had with the possible exception of Freddie (a cockatoo), I could do ANYTHING with her. Same with Zoey, I can touch and manipulate her entire body and she has never, ever, ever bit or even nipped me. Sweetpea is another story because he had lived almost all his eleven years in a small square cage, not ever coming out for many, many years (if ever) prior coming to me so he hated all humanity with a passion - but me even more because he fell in love with Tobita who adored me (but he no longer attacks me, steps up, rides my shoulder and allows me to scratch his head, neck and cheeks).
Let her come out and then ask her to step up and, if she just wants to ride your shoulder, let her. Soon she will be allowing you to scratch her head and even asking you for it
