This invention discloses a bedding material for chicken houses. The bedding material includes, from top to bottom, an ammonia-locking layer, a flow-guiding and degradation layer, and a ventilation and buffer layer, all of which are mixed layers formed by mixing various raw materials. The upper surface of the flow-guiding and degradation layer has an array of parallel, continuous, elongated flow channels. Each flow channel includes a slow-flowing section and a fast-flowing section connected vertically.
