My chickens would never make it to slaughter if I let them free range. We have coyotes, coy-dogs, red tailed hawks, owls, and my neighbors dog. There have also been sightings of bobcats. Nothing smaller than a turkey stands much of a chance. I need a meat bird that won't care about being in a tractor coop. I like the colored rangers but if they need to be free range I can't do it.
