Yup, like they said, handfeeding is a big help once they're ready for it.

Another thing you could try is putting your hand in her cage for small amounts of time, and just let it sit there and not trying to touch her or anything. That'd be a good way for her to get used to your presence and understand that you're not a threat. It's great that she's already taking food since you don't have to worry about every little thing you do stressing her out and keeping her from eating.
