A Hybrid chicken bred from a Columbian Plymouth Rock Rooster and Rhode Island Red Hen. This robust, dual-purpose bird is known for its ability to efficiently produce eggs even in the coldest of climates. An excellent layer of cream-colored brown eggs with a calm good-natured disposition, this cross is a great choice for the family flock. The Columbian Rock cross bears a heavy resemblance to its male parent. These birds will not breed true.
