They don't free range well... they can... but unlike a layer, don't glean much from things on the ground. They rather just poop on everything.
I have to disagree, at least with my birds. I have the cornish x from Meyer hatchery (I don't know if there is a difference). I have switched them over to scratch feed for the last 2 weeks (they have a date with a hatchet next week), but they are far more interested in bugs and weeds (particularly plantain) than thier feed. They still go through a good deal of it, mind you, but with 25 birds, the 50 lb bag still lasts about a week. Due to the free ranging, they are considerably smaller than others have reported growing thiers-- no 10 lb 8 week olds here, the one that I butchered last week (she was a little older than the others) dressed at 3.4 and had more meat than the 4 lb birds I buy from the store. Also, she didn't have much fat on her. We are happy with the results.
I would be leery of growing them to 12 weeks, likely they will have heart failure problems.
