It's my understanding that cornish crosses are hybrid birds. Therefore if you buy a flock and manage to get them to breeding age they wouldn't breed true anyway. (even if they managed to successfully mate - I have read that the cornish cross roosters get so breast-heavy that they literally can't mate and therefore the eggs are artifically inseminated). I have raised them, butchered at 8 weeks and yes they taste just like supermarket chicken.
Red rangers are the meat "breed" that I love to grow. They take slightly longer than a cornish cross, I butcher at 10 weeks, but the taste/texture is the same at that age. We grow them out in a large pen on grass. If you let some of the hens get older they lay large brown eggs and mine have gone broody/raised chicks for me.
I have a Brahma rooster that mates the red ranger hens. The offspring are huge, gentle and beautiful.
As for the "supermarket" taste: the flavor and texture of grocery chicken comes from being butchered at such a young age and not being able to move around much. The older a chicken gets (the more it is allowed to, god forbid, run, flap it's wings and be a chicken) the more "chicken-y" the meat will taste, the meat will look darker and will be more fibrous. Frankly, I've come to appreciate the flavor of a chicken that's had a longer life.
