I've raised Freedom Rangers for maybe 6 years years, this year and last starting with 50. Once they are out of the garage brooders half go into a 4'X10' coop in a maybe 1/4 acre fenced run and the other in a mini-van turned chicken coop with an attached 12'X5' tractor/run. We have a lot of predators here, so we need to be sure they are secure, really secure at night. The tractored Freedom Rangers are moved every day, and during the afternoon when I'm home and the dogs are outside I let them free range for a few hours. I've never lost any to a predator, but they don't wander far.
Personally, I like the taste and texture of the Freedom Rangers way more than CX. There is a bit more dark meat and a bit less white meat, and there is more texture, but I would never call them tough. You are butchering at 9 - 12 weeks, rather than what...7-9 weeks with the CX so they are still young.
