Animal droppings for compost

Many gardeners buy compost starters to get a pile fired up. These are basically high-nitrogen products that may or may not work, depending on what else is in your pile. Fresh green weeds, with a little soil clinging to their roots, or a shovelful of soil or compost, tossed at intervals into the pile will suffice. But for a great, cheap pile activator, try alfalfa. Toss in handfuls from bales (old or rained-on bales are the cheapest) or use an alfalfa meal product. Horse feed, rabbit food pellets, even some brands of cat litter, are almost pure alfalfa meal.

Pets, except dogs and cats, can contribute significantly to the nitrogen content of a compost pile, some will even do the work of turning
If you live in an area where it is possible, and you like animals, keep a pet rabbit or some chickens. Rabbit waste, collected in a bucket beneath the hutch, is high in nitrogen, a fact attested to by the urea odor. But emptied routinely into the compost pile, you avoid the odor, while adding its riches to the pile.
Chickens are even better than bunnies. Toss your compost materials into an enclosed chicken run and let them turn it all into a homogenized, highly nutritious blend. Every few weeks rake out the run and add to the compost pile. Chickens will also produce fresh eggs for breakfast, and they love to eat garden bugs!
