I had great success with the CX this year...my first time growing them. I free ranged them with the rest of my flock and they developed nicely.
Yeah, they don't act like normal chickens when they get some size on them, but when they were smaller they acted just like all the rest of my chickens...they foraged well, loved following the tiller for all the worms and bugs and they were nice and quiet.
Until feeding time. Then they would get into a frenzy and crowd out my regular flock but I would solve that next time by keeping them and ranging them separately.
They really loved the free range life and had developed very strong bones and they had healthy organs.
I didn't feed high protein feeds nor did I feed free choice. They had to walk a steep ramp to get inside the coop and they had to walk outside again and across the orchard for water. This seems to have served them well. I didn't lose one bird and none of them ailed a day...two even got severely injured early on and healed completely and quickly.
I can tell you this...I harvested 100 lbs. of meat from 20 birds and the processing was the easiest processing I'd ever done. Everything on these birds was so tender that there was no effort to pluck, the joints cut easily, the feathers and entrails had no strong smells....it was rather pleasant.
And the meat??? It is so tender and juicy, so flavorful...nothing whatsoever like the birds in the stores. These birds were clean, had clarity of flavor...almost like a wild turkey tastes. Excellent!
I will raise more next spring for sure. I'll do it a little differently but they will still free range, they will still only get fed once a day, and they will still get plenty of exercise, green forage and good living.
No Frankenchickens here, folks!
