So there's a few chickens who sleep ontop a tall stack of drawers and there's a box ontop and they all sleep ontop around it. Left it there for some months, so during those few months it filled up with their poop and I just cleaned it out today. But there were these bugs/grubs/insects? Living inside it, they were everywhere, squirming around in the poop? Pics: What are they? What insect do they belong to? How'd they even get there? Can I farm them?
