Easy instructions, easy set-up, easy maintenance ... and super-easy on the wallet! Harvesting is easy, too. Just pick up a scoop with a dollar-store kitchen sieve and shake it gently. Smaller worms and eggs fall through. Live beetles crawl over the edge, leaving the dead ones in the basket as extra chicken-treats. If you want to keep the pupae, just flick them out with a finger-tip - and if you pick your scoop carefully, you may not even have to do that!.
I never thought of doing that. I just used a old jar and my hands. I pick out the worms, put them in the jar, then feed them to the chickens.
Rest assured there are plenty of dead beetles in mine. The worms will eat those as well.
