The hatchling male I produced came out on 7/29 and already weighs 146g. I agree with first post--she may just be using all the nutrients and have nothing to poop out.
A lot of my Balls take a couple weeks or more to take a full on dump. But during the time they'll pass urates and such. She'll pass it soon enough. I would definitely consider switching her to larger prey and to rats. by 8-9 months she should be over 500g at least.
