If you have rabbits, you have manure to manage. Whether for pets or meat, rabbits produce a lot of manure for their size. An adult rabbit will create about 50 lbs. of manure per year. Rabbit manure is nutrient-rich, especially in nitrogen, and is a dry pellet that is safe to put directly into gardens or feed to worms. Raising rabbits and worms can easily go hand-in-hand with beneficial results. Building a rabbit hutch with a worm-composting bin is an excellent way to manage the manure, create a garden-soil additive and even raise worms for sale.
