help with RTB please

[John Petitt]

I have my first RTB (used to having BPs) and am just wondering how often they use the restroom. my BPs usually once a week-2 weeks after feeding. if they don't poop by then i soak them and try to let them work it out which usually works. if not i try to force it if it feels like it may be calcified. but anyway my RTB ate about 2 weeks ago and still nothing (even after 2 soaks and i feel a tiny bumb of poop that's it). is this normal for that species?

thanks.

*edit

feeding it hoppers. and is only a baby RTB (BPs are 4 months and 2 years)
