A Cornish X will weigh about 3 times that of a Buff Orpington (dual purpose breed) at 5 weeks! From hatch to slaughter weight in 6 to 8 weeks, some hatcheries claim 9 1/2 pounds in 10.5 weeks! Processing is much easier with Cornish X's than a dual-purpose bird because they have very little feathering at slaughter age. Probably the only other reason why this bird is used so much by the processing/packing industry. Cornish X's are not self-sufficient. The best results after brooding seem to come from those who raise in a chicken tractor, moved daily (sometimes more), and a ration of high protein feed. Rationing the feed 12 on, 12 off, seems to encourage the Cornish X to forage and get some exercise. If not, they tend to stay right by the feeder making a very concentrated mess. Some problems that may occur if pushed (or even just because of their genetics) are heart attacks, broken legs, and FLIP. The reason for the main image is because that is their intended purpose... FOOD!! Yummy!!!!
