Housing and Husbandry of Laying Hens: past, present and future
This review briefly traces the origins of the domestic fowl and its spread throughout the world. It goes on to consider important historic, traditional, conventional and modern developments in the housing and husbandry of laying hens. These periodic terms are used according to the definition of Gordon and Charles (2002) i.e. historic: pre 1914, traditional: […]
