We just cleaned 60 Cornish X birds at 6.5 to 8 weeks of age. I cleaned a Game fowl rooster today. The skin on the CX's just peeled right off and we had to be careful not to tear it. The Game's skin was like trying to tear leather. I had to cut it. I can't imagine chewing that stuff. Does it get better (as in more tender like a store bought chicken) with cooking?
