Ahh, composting. One of my favorite subjects! We live on 10 acres but our only livestock are our chickens. I collect from the girls once a week, inside and out of the coop because the coop is a little small I want to keep it fresh as possible. I do collect poop from a girl down the road that has 101 rabbits, (just so she can say she has over 100), and any multitude of goats, calves and a donkey. i end up usually with close to 400 pounds of manure a week! My oldest pile is 10 ft x 10 ft x 12 ft high. Once a week with the front end loader I go out and toss it around. My new pile isn't that big yet so I don't do anything with it until after winter. This helps get the right balance before I start mixing. I alternate between these 2 piles on a yearly basis. Our garden is 200 x200 and I sell our extra produce to a gentleman that operates a veggie stand a couple miles from our place. Thinking about a third pile!
