Jumbo Cornish Cross

Breed Development and Purpose

The Jumbo Cornish Cross is a commercial-type meat bird developed specifically for rapid growth and high feed efficiency. This cross combines Cornish and White Rock genetics to produce a fast-growing broiler suitable for meat production.

Unlike heritage dual-purpose breeds, the Jumbo Cornish Cross is bred strictly for meat performance rather than egg production or exhibition.

Customers seeking a heritage meat breed may also consider the White Plymouth Rock Chicken Or the Black Jersey Giant Chicken

Growth and Feed Conversion

Jumbo Cornish Cross birds are known for their rapid growth rate and strong feed-to-weight conversion. When managed properly, they can reach market weight in approximately 8 to 10 weeks.

Because of their rapid growth, careful management of feed and activity levels is important to maintain bird health.

Temperament and Management

These birds are generally calm and less active than heritage breeds. They are not well suited for free-range systems or long-term egg production programs.

They are intended primarily for short-term meat production cycles.

Egg Production

Jumbo Cornish Cross birds are not selected for egg production. While hens are capable of laying, egg output is limited and not the primary purpose of the breed.

Availability

Cackle Hatchery® offers the Jumbo Cornish Cross for customers focused on meat production and efficient broiler growth cycles.
