Mega-
Yeah, they need additional nutrients that they can't get in their enclosure, ie Calcium, the crickets don't need the dustin at every single feeding- especially if you are going to start feeding daily- but about every other feeding should suffice. It sounds like your crickets are getting what they need to stay healthy and provide proper nutrients to your FBTs. I do the same about getting a bigger number at a time since I too have to drive to town to get them. I did however, have to find a number that is enough to feed them for awhile but not too many that they would die on me. Anyway, sounds like you are on top of the cricket thing. Keep us posted on how she does with the new feeding schedule.
