I have 4 cubic yard plastic bins, and right now I have 2 that are full of ready compost. I put all the litter and cleanings, plus household garbage and some lawn/garden waste in them. Once I started using chicken droppings I no longer had to suppliment the nitrogen. The only thing I changed in the coop was to go to shredded paper as the bulk of the litter. I shred all waste paper that isn't shiney or overly colored. I put pine shavings in the next boxes, but the girls toss paper in there also. When I first started I would clean the chicks up often, and put the barely soiled litter in the bin, and that first bin took nearly 6 months to show any significant decomposition. Now I toss the nearly clean chicky litter into the coop and let the wood absorb more poop, and that has speeded up the composting. Ugh, the coop is getting due for cleaning, but I think I have enough room is the working bins still. It amazes me how much the materials are reduced when the compost is finished. At least now I don't worry about running out of compost. First time in my life.
