my baby BP hasnt pooped in ages

lol i guess i should be smiling but now its worrying me.

his last poop was atleast 2 months ago.

i made a mistake in ordering pinkies to start him off on, though. and then i ordered hoppers but perhaps theyre just too small for him? they arent nearly as wide as he but i give him atleast 4 or 5 a week. maybe that could be why?

he isnt skinny but he isnt fat. and he looks totally fine, eats fine, and seems to urinate fine.. just no poop.

theres no bulges at his lower end of anything.. should i be worried? or should i just feed him more? he doesnt look under fed to me. but is more of an oval shape than a pure round one. shall i feed him 'till he's round? lol..

ive also heard stories of baby BP's eating their own poop. i really doubt this is the case but what do you think?
