Vents for easy DIY Mealworm farm

We have chickens.
Thanks to my wife, they are spoiled.
Spoiled rotten chickens (and wife, she's spoiled too!)

I wanted to start growing our own mealworms for treats and tried a couple of different ideas with varied levels of success (and escapism!)

This is my final design and it works wonderfully!

Uses a Sterilite storage box (we bought them at Hobby Lobby in a 2 pack) but other stacking/locking boxes would work equally well I would think.

Just print a bunch of the vents out out.
