There is so much Cornish X hate here. They are not "mutants" or "frankenburds" or "gmo."They are just an extra large terminal cross. Mine run around, argue with each other, scratch, and hide around under trees. Ya know, like a real live chicken. They weren't made in a lab or hatched out of fake shells. There are enough insane conspiracies out there (that are probablhy true, like the moon landing!) to believe in. Leave the noble Cornish X out of it. They may not be the perfect heritage bird, but it is thanks to them we can all afford to eat chicken.
Keep heritage birds for a conservation hobby. They are beautiful, and a rich part of our nation's history. Stop pretending they even COMPARE with Cornish x for efficiency or cost or that Heritage birds can efficiently feed a family of four year round. No amount of "that indescribable heritage taste" is getting me to pay $8/lb for chicken.
Stop hating on Cornish X. They are just a symbol of what for what you hate...the fading "death" of the old ways. But realistically, Cornish X made chicken the staple food it is today.
I don't eat cornish x because they are tasteless.
