Feeder breeding drought...

I went to the local pet store yesterday looking for live feeders and their selection was almost non-existant.. The girl said they had a breeding drought so all they have right now are adult mice, pinky mice, and juvi to large adult rats. I ended up buying 3 pinkies and Sasha ate them live, one after the other. I tried F/T but she shows absolutely no interest. Is it better to feed her 2 or 3 of a rodent that's too small or try to drop one in that's bigger than her width? I'm thinking she might be able to take on a small adult mouse...
