Well it sounds first of all that you have poor humidity. That can easily be fixed with spraying warm water into the tank. Winter months are always a little dry in my area. As well as covering any open screening.
Secondly totally stop the moving her for feeding. That's a garbage myth that's gone around for years. Feed her in her cage. Just drop the food in and observe for any issues. If she doesn't eat it take the food back out. Also your feeding an adult female, mice? How many how offer? Do you know her weight? Do you know the weight of the prey? Prey should equal 10-15% of the snakes total weight. Personally I'd try small rats. Most of my adult girls can chow a couple weanling rats or a medium small adult rat.
I think what you could be seeing is a female who's coming into a building cycle. I have a few females that are ravenous here. They're preparing to breed and whether you breed her or not she can still cycle herself. Try giving her more space and upping her prey.
