Ball Python Issue

Definitely sounds under nourished to me as well. My male BP, a June 2012 hatchling so not much older, started off eating mouse hoppers from the get go. Pinkies don't have the same nutritional content as the older rodents; they're lacking a more structured bone system which means your snake is not receiving appropriate calcium and other nutrients that bones provide. I'd switch them both up to hopper mice or fuzzy rats once every week. The can eat a lot larger prey than you'd think. Also, if she's refusing to eat, you might do a re-check on your husbandry. If they don't feel secure in their environment, they won't eat.
