One can produce a lot of red wigglers with a rubbermaid container or two. My worm bin doesnt smell. It is outside, but some people keep one under the sink in the kitchen. Rabbits droppings under a cage hold a lot of earthworms outside. If you have a rabbit/rabbits tehre are a lot of worms underneath the cages in the droppings. The droppings make excellent fertilizer that doesnt need to be composted, as it is not hot like chicken poop. If you have no aversion to it chicekns and ducks will eat the hay seeds that sprout out of the top of the pile if you have a ahay manger. They willscratch around in the pile too for worms if you dont want to dig around. My coops and cages were meant to move around so they would get auto composted.
