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.
Yokohama chicken The Yokohama is a German breed of fancy chicken, with unusual colouring and very long tail-feathers. It was created by Hugo du Roi in the 1880s, and derives from ornamental birds brought to Europe from Japan in the second half of the nineteenth century. Some of these were shipped from the Japanese port of Yokohama, and so were known by that name. In Germany, the Yokohama name is used only for white or red-saddled birds; in the United Kingdom, it is used also for the birds known elsewhere as Phoenix, in various colours.
