We have use rabbit manure on the garden for many years. They produce about 2 wheel barrels a week of pure pellets and urine which is placed directly on the veggie garden during the late fall and winter months. In the spring it is tilled into the top 4-5 inches, the garden is tested for ph levels and limed to adjust to proper ph 2 weeks before planting. During the growing stage of the garden fresh rabbit manure is mixed with Canadian peat moss and used as mulch. We get huge amounts of production with this method.
