Recognized by the American Standard of Perfection as a distinct pure chicken breed in 1874 and known as the kind of chickens that "Grandma" use to raise. Barred (black and white lines) is one of the color varieties of the Plymouth Rock Chicken family and an excellent winter/summer brown egg layer. The Barred Standard Plymouth Rock Chicken is a great backyard hen for egg production and kid friendly chicken. Most people call them simply ” Barred Rocks” which is a short name for the Barred Plymouth Rock Hens. Some people confuse the Barred Rock chicken with the Dominique chicken breed. The Dominique chicken has a rose comb and a slight v pattern in the barring of the feathers. The Barred Rock as a single comb (straight comb) and has more of a straight pattern in the barred feathers. Both make for good chickens in the winter and good pet chickens.
