The Ancona chicken breed was named after a town in Italy, which is their origin. Ancona chickens were originally known as Black Leghorns because of their color, which is black with evenly white-tipped feathers. As with Leghorns, Anconas are known primarily for egg-laying and produce large numbers of white eggs. They were once one of the prime egg-producing breeds in Europe, and joined American farm flocks in the 19th century. They are a hardy breed which does well in both cold and warm climates.
