Cornish Cross is one of the most popular meat birds. At about 6 to 8 weeks, they can weigh anywhere between 4.5 to 6 lbs. Heavier weight can happen depending on the final grow out duration. It has been recorded some Cornish Cross reached 10 to 14 lbs using a well-managed care and feeding program. This breed is known for an excellent feed conversation, livability, strong legs, and a maximum white meat yield with a plump full confirmation.
Cornish Cross have a docile chicken with very little interest in anything other than water and food. They grow so quickly so their attitude and temperament is rather low compared to most other breeds.
This chicken is not one you would get if you are looking for great egg production. Cornish Cross usually have significant health issues by the time they hit 8 to 10 weeks because of their rapid growth. There have been cases people have been able to keep their hens past their slaughter date, but it not recommended for this breed.
