Careful with these dudes, the boys are incredibly aggressive to other boys. Just not to poeple. You might contact a couple that have posted regularly here. They might have some eggs in the spring that are at least partly exhibition quality cornish. You already, hopefully, see the difference in width between the hatchery dude and the nice girl. The boys are the same. They are bulldogs though. hehe. You have to treat them as such.
The story I read about someone seeing a coyote running and 40 LF Cornish chasing it, I don't doubt ONE BIT. As that fella said, "what a chicken!" - They are. The hens wont' start a fight with other breeds, but brother, if the others start one, they'll sure finish it!
