i think i use the deep litter (or bedding!?) method. it is really just that i'm lazy. this works best in my chicken barn that sits directly on a stone dust floor. they poop mostly under the roost and i just keep layering on more hay, shavings and leaves into this area. i sprinkle this stuff every day. in spring, this stuff has mostly decayed into mulch. i use it directly as a top dressing in gardens. it is an awful job getting it out--stinky. every time i "wake up" a garden i pull some out until the barn is clean. it makes my gardens grow like crazy. i have a big barn and not too many chickens. i'm by no means commercial. just backyard. the barn is warm and cozy because of the deep litter.
