Diriya Farm raises chickens according to free range standards and sells eggs in their local community. The pasture area is a home garden with shade, vegetation, access to fresh water, and protection from predators. The birds have enough space for natural behavior. Poultry litter is donated to local farmers as organic fertilizer. Diriya Farm works with Sri Lanka Human Development Foundation to promote natural farming techniques and reduce carbon emissions. They are verified free range under a local participatory guarantee system (PGS).
