A growing number of poultry farmer field schools (FFS) are being implemented in developing countries by a wide range of actors. Experience over the past two decades has shown that good-quality facilitation and learning activities are key to the success and long-term sustainability of poultry FFS. This manual provides practical information and activities that help facilitators establish and implement good-quality FFS. It focuses on working with women and men poultry producers to sustainably enhance production, productivity and marketing in any family poultry production system, ranging from extensive to small-scale intensified, in line with producers' aspirations and local conditions. The first module of the manual covers poultry FFS establishment and learning activities, and the second provides 'need-to-know' information on poultry production and health and FFS facilitation
