Here are the plans I followed to construct the worm bin:
It was very simple. I asked the worker at the hardware store to do all the cuts for me, expecting to pay 25 cents per cut, but he gave them to me for free. After that, I only needed a screwdriver and a few other non-power tools. It took one afternoon/evening.
Just need worms and some junk to go in there. The chickens produce lots of “junk” (and so do we, in the form of table scraps and yard clippings).
