I use oats too, and they fight over them (cute!), but keep your veggies away from your oats!! I had a mold problem last night. So now they can't be feeders for a while. Granted, they haven't been feeders for a while anyway, which is how some oats got moldy (tossing in food without really paying attention). If they died, would be ok, but they're hopping around instead. Pulled out 3 dead, 1st time I've removed any since I added 50-60 maybe a month ago, not sure. More crickets means more deaths. Overcrowding means a lot of deaths. Mold and cold are the biggest threats that I know of. Oh, and unwashed leafy greens. Wash your kale.
