This is a larger scale, but we have 2 homemade cricket keeper boxes at 8' long, the adult breeding side is 28"x6' with 2 egg laying bins, we rotate the egg laying bins every 4 days and move them to incubation, typically 10-13 days in incubation at 87 degrees for hatch. The adult side houses around 2000-4000 crickets at any given time with very minimal death. We like to use the water crystals for watering as it's just easier with 5 small trays, we keep 6 food trays 2 for dry feed and 4 for fresh food gut load. This really just works for us, we do have a lot of reptiles to feed, with around 60 or so reptiles it takes 24 8.5"x11"x3.5" cricket egg laying bins, and 15 30 gallon incubator and rearing totes to keep up with the rotation. This could easily be scaled down. For good breeding, the temps should be 85-87 degrees, the females will lay eggs every 2-3 days, so keep the egg laying bins in for around 4 days to be positively filled with eggs, we use a mixture of play sand and peat moss at roughly 1.5" thick.
