Are you feeding her live or frozen/thawed? Do you know what they were feeding her before you got her? If she was being fed live before, and you are trying to feed f/t it may take some time. If you've only had her a few days she may need more time to get acclimated from the move. How are you trying to feed her? Do you just leave it in her tank for a while? I've had to do that before just leave the mouse in the warm side of the tank at night and in the morning it was gone. I've found with my normal at least that movement is the key. I just jiggle it back in forth in front of him and he usually strikes right away. Do you know how much she weighs? If you don't have a digital kitchen scale it is a good investment (only 10-15$) The general rule of thumb for young snakes is to feed 10-15% of their body weight as long as the prey at it's widest point is not larger than the snake at it's widest point. I.E if your snake weighs 150g then you should feed a prey item that weighs between 15g and 22g. From what I've heard a slightly smaller prey item would be taken more readily than larger, but at some point if it's way to small they might not see it as food.
