I've been using a sort of modified "deep litter" method since getting my chickens in April. Put them in the outside coop around the end of May. Using straw for about 4" deep litter. Haven't changed it so far. I do turn the litter underneath the roost every couple/three days using a three-pronged garden soil hand tool. I sprinkle DE if the coop starts to get a smell. I have removed a small portion of the litter about 3 times, and threw in a flake of hay, about 4". I use two of those "tree" vanilla hanging car deodorizers. (really!) which helps keep the fly population to a minimum. The floor of the coop is oil-based painted wood, which creates a slick, non-stick, non-porous surface. I find that the litter does not actually compost with this method; it dries out. The poop gets to be little hard balls, which stay that way till it goes into my compost pile with the hay I have removed. Yesterday I found I could use the three-pronged tool in one hand, and a dust pan in the other, and sucessfully scoop up soiled straw, rake the straw off and have the poop balls remain in the dust pan, to be placed in a bucket headed for the compost pile. This saved more straw. I only did this under the roost. I kind of stir the straw around in the rest of the coop, to keep it fresh. The chickens assist in this. Honestly, I don't spend more than 15 minutes a week cleaning inside the coop. I rake around the yard just about daily, trying to get most of the poop out of my path. That takes very little time, as well. My coop doesn't stink. The yard only stinks if it has just rained. A liberal sprinkle of DE in the yard takes care of that.
