I raise a flock of 100 Cornish Rocks every year, in 50 chick increments, for meat. These are the chickens you will eat if you purchase your meat at the supermarket. Also known as factory chickens, and Cornish Cross's these chickens grow astoundingly fast. At just eight weeks they are ready to butcher at a solid 5 to 6 pounds. Compare this to a heritage breed that would be only 2.5 to 3 pounds at the same age. The meat to bone ratio is also exceptional. This breed grows it's muscle mass before it grows it's bones. The downside of this for the chicken is that it cannot support its own weight by eight weeks, and they are plagued with heart problems. The mortality rate after eight weeks is very high. These chickens are best raised in large pens, or on the floor. They are pretty birds in my opinion but they look monstrous next to similar aged peers of heritage breeds. If you're wanting your chickens for meat the Cornish Rock is the only way to go. The only thing that comes close are a few breeds that have only been developed in the last few years in the Freedom Ranger, and Rainbow Ranger.
