Years ago, a small, amazingly productive chicken breed was imported from Italy through the port of Livorno. “Leghorn” became the Anglicized word for that port and the breed. Supermarket eggs are almost always laid by White Leghorns or hybrids developed from them. Hens lay about 325 large white eggs every year while eating less feed than most other breeds. They are perfect for a family wanting abundant white eggs. Leghorns are nervous nellies that can fly over fences. They weigh approximately four to five pounds fully grown. Chicks are light yellow with orange feet and beaks.
