Basically the deep litter method is a big compost pile that is aerated and turned via chickens. I've got a least an acre to mow and roughly 3 acres of woods (for leaves to add to the mix), so this method seemed ideal to me. Plus, I'll be using deep bedding in the coop and during the yearly/twice yearly cleanout, I can just toss it out into the run as well.
I'm a bit excited about it as we have a heavy clay soil here, so I've been using raised beds to garden. Next year I expect I'll have a significant amout of nice fertile compost to till into the clay, which will let me expand.
