Barred Plymouth Rock Male from American Standard of Perfection 1947

The Plymouth Rock was developed in America in the middle of the 19th century and was first exhibited as a breed in 1869. Several individuals claimed its invention, using crosses of Dominique, Java, Cochin, and Brahma. The first Plymouth Rock was barred and other varieties developed later. The Breed quickly became popular due to its qualities as an outstanding farm chicken: hardiness, docility, broodiness, and excellent production of both eggs and meat. Originally the name Plymouth Rock implied a barred bird, but as more varieties were developed, it became the designation for the breed. The Barred Plymouth Rock was one of the foundation breeds for the broiler industry in the 1920's.

In Australia the Plymouth Rock is usually seen in the Dark Barred variety. Light Barred and other colour varieties are rare.
