Delawares, originally called “Indian Rivers,” were developed by George Ellis of Delaware in 1940 and were used for the production of broilers. The breed originated from crosses of Barred Plymouth Rock roosters and New Hampshire hens. A few off-colored sports were produced that were almost white with black barring on the hackles, primaries, secondaries, and tail. This coloration is very similar to the Colombian color pattern, but with the barring substituting for the black sections. For about twenty years the Delaware and the Delaware x New Hampshire cross were the most popular broiler chickens on the Delmarva Peninsula, because of the Delaware’s ability to produce offspring with predominately white feathering. This is an advantage for carcass appearance since white feathers don’t leave dark spots on the skin when feathers are growing in. Both the Delaware and the Delaware x New Hampshire were replaced in the late 1950's by the Cornish x Rock cross (solid white) that has come to dominate the industry.
