Leghorn chickens originally came from northern Italy and were brought to American by Captain Gates in 1852.
These are not heavy birds – the standard male weighs about 6 lbs and the female weighs about 4.5 lbs.
There are several varieties of the breed – white, red, black tailed red, light brown, dark brown, black, blue, buff, Columbian, buff Columbian, barred, exchequer and silver.
They lay about 280 white eggs per year.

One of the most famous Leghorns is the Looney Toons Foghorn Leghorn character.
