I will disagree a little bit. I don't know exactly how many they are feeding at a time, but personally if I had a mouser female like that I wouldn't feed only 10-12 days apart. A mouse is such a small meal for a large adult female. They'll digest them a bit quicker as well.
It would take a bit of time to figure out the exact schedule for the individual snake, but I had a smaller male who would only take rat fuzzies for a while even at 700 grams. So we did one fuzzy every 4-5 days to make sure he had some time to digest between meals. But again. It takes a while because you don't want to start throwing meals that quickly because they need to build up that stomach acid. Start on a 10 day week and every other week cut it back by one day sort of thing
In the case of a large adult female like this I'd probably see if I could get them to eat one mouse every 3-4 days vs trying to feed multiple mice in one meal. Or at the most 2 mice every 4-5 days.
Of course, once the snake is a good body weight, you can test and see just how much they'll maintain in body weight when spacing out food a bit.
