It is different because the Cornish are bred to grow so large and so fast with no attention paid to thier ability to walk and they may even suffer discomfort such as joint pain from too much weight on undeveloped joints, there is mention of sudden death from heart attack, which might naturally indicate that those that do not die from heart attacks might be suffering from the symptoms of heart strain such as fatigue, shortness of breath, hypertension. While the birds do grow quickly and cheaply, it would be insincere to pretend that they (the meat birds/cornish X) don't pay a price for that thriftiness.
While people also breed birds for appearences using selection techniques for certain traits, they do not for the most part ignore the negative traits that pop up in favor of that big crest or whatever. It would be useless to breed an ornamental for having really good leg feathering if they dropped dead of a heart attack or were unable to walk. Good breeders would not encourage traits that don't allow an animal to thrive. my polish have huge crests, yet they can walk around and forage. Iv'e seen cornish that can't even walk. Big difference. (In terms of the effect of selective breeding on the birds quality of life)
