I have tired many different things with my balls, but some are just bad eaters. Some will take f/t, some won't. Some will eat every week, some every other week, and some like to take months off. That is one reason that I am selling all of my ball pythons, and switching to snakes that eat very well on f/t. It is just so frustrating when you breed your own rodents. You never know how many to breed because you can never determine which, or how many, balls are going to eat each week.

Good luck though.
