Get yourselves a Phiomia as well! Feed it stimberries and you'll have plenty of medium feces to throw in the dung beetle. Fill it up, and come back and watch more fertilizer than you can imagine. I'll never use compost bins again!
Turns human and dino poop into oil and fertilizer. Make sure the dung beetle is on wander and has plenty of poop, it takes about 15 min per cycle.
1 Human poop becomes 1 fertilizer and 2 oil
2 Small poops become 1 fertilizer and 2 oil
1 Medium poop becomes 2 fertilizer and 4 oil
1 Large poop becomes 3 fertilizer and 6 oil
1 massive poop becomes 16 Fertilizer and 14 oil.
Every cycle can do one "transaction" for each type of poop for a maximum of 7 fertilizer and 14 oil without massive poop or 23 fertilizer and 28 oil with a massive poop.
My tribe has a larger 'wandering room' upstairs where we have multiple dung beetles and snails. They tend to naturally group up in the middle of the room so they're easy to manage. Just watch out, they can escape through an open door or glitch through the ceiling to the level below. You also can't pick them up when you have a shoulder pet on.
Feed it small feces! The dung beetle will produce fertilizer no matter the size of the feces you put inside his inventory! Using small feces weighs about .3LBs meaning you can stock his inventory extremely well and get tons of fert back.
