McMurray Hatchery Jumbo Cornish X Rock

Our Jumbo Cornish Cross (Cornish X Rock) is the most remarkable meat-producing chicken we offer. The Cornish Cross is a hybrid developed by crossing the commercial Cornish chicken with a White Rock chicken.

Selective matings produce baby chicks with broad breasts, big thighs, white plumage, and yellow skin. These broiler chickens are known for their remarkable, rapid growth and feed efficiency. Whether you are looking to raise these top-selling meat birds for your own pleasure, or to raise and sell, you won't find better.

Females will have a fine, smooth finish when dressed, and reach beautiful roasting size. Buying straight run chicks gives you some of each sex so that you can take advantage of the strong points both ways. Males are ready to process in just six to eight weeks, and females will take about one and a half weeks longer to reach the same size.

Our Jumbo Cornish Cross (Cornish X Rock) are among the finest meat birds in America — we fill our own family freezers with them every year!

Not recommended for raising at altitudes above 5,000 feet. 

Jumbo Cornish Cross are hybrids, therefore we do not recommend breeding. They will not produce the same high quality in the next generation and due to the extreme rate of growth they will be too large at time of sexual maturity to breed successfully.
