You're wrong. And tons of information on the net will prove it. These crosses are bread to eat continuously so they will reach market faster and at lower cost. The problem arises when there hearts can't keep up with the amount of weight their bodies are packing. A lot of these die from heart failure or heat exhaustion due to this bulking process. I also lost some because of this.He is probably referring to the Cornish x Rock crosses used for meat birds. I raised 30 of these last year. They will eat themselves to death if you leave food in front of them. And they don't like scavaging for food as much as other breeds from what I've read.
Cornish-Rock meat birds will not eat themselves to death. In fact, the normal procedure raising them is to have food available to them 24/7. Some will become so heavy that they can't walk properly, but they won't die from overeating.
You must be keeping them past the 6 weeks or so intended for broilers.
Cornish-Rock crosses are broiler chickens - meant to be harvested at 4-8 weeks max. During this time, the standard practice is to give them free access to a high-protein feed 24/7. If there were significant deaths during the raising it would not be profitable to do this.
After the broiler stage, you're probably right about health issues being problematic.
