I have 3 compost piles going for the spring garden... My husband made me a side by side bin that I filled BOTH sides up completely within a month. We had a corner spot in the pasture where I had a big round bale that had composted down. Each time I'd clean the coops and barn, I just started throwing the waste in that corner spot. Now I have a big compost heap that is probably 15' x 15' full of hay, pine shavings, straw, dead leaves, and manure (goat, chicken, horse, and duck).
Today when I cleaned the coops, I stuck the pitchfork to the bottom of the corner spot to look at how it was progressing. Two words - black gold. About 4 inches deep so far that's already completely composted. That's not counting the other 4+ inches that is still composting. It's gonna be a good year.....
