I was on your shoes too...well it probably will take a while since its in its new home...it'll take about a month or so or maybe just weeks...but remember to keep on feeding it on a regular schedule don't stop feeding it if it doesnt poop...after a while its going to poop every week or so...
My female BP (800 grams) eats regularly but only poops sporadically. Sometimes she will go weeks without pooping. Right now it has been darn near a month since her last huge pooper but in the months time she did get finicky and didnt eat for two weeks so that is what I attribute the "no poop" to.
