The Dung Beettle is awesome and crucial for fertilizer production. Keep the beetle in the corner of the main area your tribe has the most traffic again. I have my beetle next to our fabricator and Smitty in the corner with the door frame to get in and out to keep it full of poop. As long as there's players around it it produces more fertilizer just like the tames when they drop eggs around more people.
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!
