Specimens of the barred Plymouth Rock were first exhibited in America in 1869, and stock reached here in 1871. The white and black varieties came as sports. About 1890, the buff was exhibited in America and in England. The barred Rock came to us as a dual-purpose breed, but was developed to an exhibition ideal in which body size and frontal development were neglected in order to secure long, narrow, finely barred feathers. With the introduction of sex linkage between the black Leghorn and barred Rock for commercial purposes, utility breeders made use of the Canadian barred Rock, a bird with a roomy body, full breast, lower on the leg but coarser in barring.
