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!
Put them in a wooden cage, and enable wandering. Then use a phiomia, and force feed him stimberries for him to literally unload his feces everywhere, and you use that in the dung beetle to get fertilizer.
PC players on Lost island- I found one really quickly in the estuary swamps down the way from the redwoods castle. Once you have one or a few they will make compost bins obsolete as they make compost way faster and added bonus of oil. It was surprisingly docile in those trees too. I’m always nervous to got down in heavy tree cover cuz I’m a scaredy cat and care way too much about my Dino’s but I just landed on my argy and walked around down there on the litter islands the slitting rivers make on their way to the ocean and found in almost immediately. Also on the north east side of that river there a small shallow pond where hecka Ovid spawn for me. Enjoy.
