I have a 55 gallon drum cut in half, using the top half I put 3 layers os window screen over thae bung holes and also cut a few more drain holes in it. I use peat moss in mine, my dad gave me a good start probably about a half gallon mixed red and black wigglers. I wet down the peat moss as needed, usually 2 or 3 times a week (don't let it dry out). I feed my chicken feed layer crumbles and keep a small light on over them all the time (if they see the light everything is ok, if it is dark they will leave on you)
