Here’s the intel:
1. Set up the structure:
For a small urban system, create an enclosed area of about 16 square meters for your chickens. This space should include a roosting area positioned above the composting area. The structure needs to be secure to protect the chickens from predators, so consider using chicken wire or a similar material to fully enclose the space, including the top. Ensure there's enough room for the chickens to move around comfortably and access both their roosting area and the composting space below.
2. Prepare the initial bedding:
Begin by placing at least one-third of a cubic meter of high-carbon mulch material under the chicken roosts. Straw works well for this purpose, but you can use other similar materials. Allow the chickens to roost on this bedding for about a week. During this time, their manure will mix with the bedding, creating a nutrient-rich base for your compost pile. This step kickstarts the composting process by introducing nitrogen-rich chicken manure to the carbon-rich bedding.
3. Start the compost pile:
After a week, use the manure-rich bedding as the base layer of your first compost pile. On top of this, add an equal amount of manure from larger animals such as cows, horses, or sheep. This provides additional nutrients and helps balance the carbon-to-nitrogen ratio. Finally, add one-third of a cubic meter of food scraps and/or garden weeds on top. This layer introduces diverse organic matter and helps attract the chickens to scratch and turn the pile.
4. Let chickens work:
Allow the chickens access to the newly formed compost pile. They will naturally scratch and turn the materials as they search for insects and seeds. Over the course of a week, you'll notice that the pile spreads out, with a harder core forming in the middle. This natural chicken behavior aerates the compost and helps speed up the decomposition process.
5. Weekly maintenance:
After a week of chicken activity, it's time to reassemble the pile. Take the spread-out material and use it to form the new core of the pile, then place the harder core material from the middle on the outside. This process ensures that all parts of the pile get exposed to chicken activity and air. At the same time, add fresh bedding under the roosts to start the next cycle of manure collection.
6. Repeat and rotate:
Create a new pile each week with fresh materials, following the same layering process as before. In an urban system, you can rotate between caged and open piles weekly. For larger systems, maintain multiple piles in different stages of decomposition. This rotation system ensures a continuous supply of compost and keeps the chickens engaged in turning new material regularly.
7. Harvest compost:
Depending on your system size, after 5-8 weeks, the oldest pile should be fully composted. In a small urban system, this process might take closer to 8 weeks, while larger systems with more chicken activity might complete in 5 weeks. Once ready, remove this compost for use in your garden. The finished compost should be dark, crumbly, and smell earthy.
8. Continuous operation:
Keep the system running year-round to continuously produce compost and eggs. In a small urban system of 16 square meters, you can expect to produce about 12 cubic meters of compost annually. This system also provides a steady supply of eggs, with 8-10 eggs produced daily. Larger systems can be even more productive, potentially producing 1-2 cubic meters of compost weekly. The key is to maintain the cycle of adding new materials and rotating piles to keep the chickens active and the compost flowing.
