These bad bois are COMPOST MAKING MACHINES. They are a far better substitute for compost bins. Just keep upgrading weight and you’re good. You’ll eventually have a limitless supply of compost for your everyday farming needs
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!
