With the little Dum I think it was all about husbandry: I set him up more appropriately and with more correct temps and security and he took to eating no problem. Add lots of security with your girl (have it be blacking out a tank if you use that, crumpled up newspaper inside the tub/cage for her to hide in), maybe switch to a substrate that she can burrow in if she's on paper towels/newspaper, give her snug hides if she has larger ones, place a towel over the tub/cage and/or place her in a more quiet area of the house if she's in a more heavily trafficked area, if feeding f/t you can try leaving it in with her overnight (I place it at the entrance of whatever hide the snake is in) or heat up the feeder with a hair dryer prior to offering so you get the rat smell circulating in the room which might peak her interest. No offering more than once a week. Also if her cold side is in the 70's I'm bump that up to 77-80 cold side/ambient temps with the hot spot at the 89-92.
