This view of the interior of the BioPod™ shows us a component that is essential, whatever the bin design: means for the mature grubs to “ramp out” of the feeding medium when it is time to pupate. The ramp here is molded into the body of the BioPod™ itself. It ends at the opening into a plastic tube, through which the migrating grubs free-fall into the lidded collection bucket below. Crawl-off occurs overnight; and next morning I simply remove the bucket and offer the chickens their favorite meal of the day. (Photo by Bonnie Long)
