Does anyone have a mealworm farm? This seems to be significantly different from my red wiggler set up. My understanding is that the worms are pupae for a beetle, the beetles can't get anywhere, die and their offspring eat them. Where my red wigglers produce "castings" which are essentially high nutrient worm poop, mealworms are just food for chickens. The beetle end game is what bothers me. Any experience with this venture would be appreciated.
