I will post something quick. There is tons of info online but to do something small here is what you do.
I am new to chickens so I did do a little test with chicken droppings, the fresh poop will kill you worms so be careful.
To make a worm bin that will produce tons of worms to feed to your chickens here is what you do. Get a container, I use a decent size rubbermaid with a folding lid. drill some holes in the top. Add things like peatmoss, shreaded newspaper, cardboard. You can use leaves but I dont like it, brings differnt bugs in. you can add some wood shavings.. ok so that is your bedding(dont use garden dirt) then wet you bedding and wait a day or two, make sure its damp, not soggy. Then add eithe RED WIGGLERS or EROPEAN NIGHT CRAWLERS other worms wont reproduce in a bin. Now the first few nights you put a light over the bin(leave it open) or they will crawl out. in one corner of the bin you begin to put the food for your worms (coffee grinds, cardboard(yes cardboard), just any kitchen scraps, watermelon rinds, banana peels, bread, NO meat. In a week or so you fill a differnt corner with food. Now maybe adding small amounts of chicken poop might be ok but be careful. with in a few months you will have tons of worms. Once you notice the worms suck up into the food you added you can leave the light off and they will stay. Worms like moist bedding, not wet and def not dry. G/L
