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

Our special 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 will dress from three to four pounds in six to eight weeks, and females will take about one and a half weeks longer to reach the same size. 

We think our Jumbo Cornish X Rocks 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 X Rocks 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.
