depending on how much she weighs and her current state of health she may just be putting on some weight so she can get to a healthy adult weight. you might try leaving a dish of mealworms in her enclosure at all times and then supplementing with crickets every 3-4 days and see how that goes. mealworms are pretty small so a worm or two is barely a snack for an adult so they do have to eat a fair number of them to really constitute a meal.
