We use them as a way to convert herbivore manure into protein for chickens. We use rabbit manure and wheat bran for mealworm food, and it works really well. You can use a wide variety of things. I know there are a lot of mealworm designs on this forum, as I started with the 3 drawer systems myself. But, I found the yield was not what I need to actually replace a good portion of the chickens' diet, so we developed the Mealworm Tower to produce more mealworms on a weekly basis.
