Where did the chicken which was part of cross breed for Legbar originate?
Leghorn chicken The Leghorn ( or ; Italian: Livorno or Livornese) is a breed of chicken originating in Tuscany, in central Italy. Birds were first exported to North America in 1828 from the port city of Livorno, on the western coast of Tuscany. They were initially called "Italians", but by 1865 the breed was known as "Leghorn", the traditional anglicisation of "Livorno". The breed was introduced to Britain from the United States in 1870. White Leghorns are commonly used as layer chickens in many countries of the world. Other Leghorn varieties are less common.
Bresse Gauloise The Bresse Gauloise is a French breed of domestic chicken. It originates in the historic region and former province of Bresse, in the regions of Rhône-Alpes, Bourgogne and Franche-Comté, in eastern France. Because of legal restrictions on the use of the name, only white chickens raised within that area may be called "Bresse"; outside it, they are given the name "Gauloise"; the breed name combines both. Four colours are recognised for the Bresse Gauloise, three of them linked to areas within Bresse: the Bresse de Bourg is "grey" (silver-pencilled); the Bresse de Bény is white; the Bresse de Louhans is black; a blue variety has recently been created. White Bresse de Bény chickens and capons raised in the area of Bresse have "appellation d'origine contrôlée" status and are marketed as poulet de Bresse; they are regarded as a premium product and command higher prices than other chickens.
