Volailles de Janzé is poultry reared in the open air in the region of Ille-et-Vilaine and the neighboring cantons in France. The chickens, pullets and capons feed on a diet based on cereals and vegetable proteins. The capons' diet is supplemented by whole milk that gives their meat a rich, unique flavor.
Since the beginning of the 20th century, the market of Janzé was famous for its poultry meat with excellent organoleptic properties. All the poultry meat is white except for the guinea hen, which is of a darker color and tastes similar to game meat.
