You can grow a cornish cross to butcher weight in that same five weeks if you let it stuff itself on unlimited feed, just like the feedlots do. Of course that's how you get the birds that grow so fast they cripple themselves or die of heart stress.... just like in the feed lots. Conscientious producers limit the feed and let them pasture, and they end up with the same bird but healthier and happier at 8-12 weeks. Growing them out at five is about maximizing profit. Letting them be chickens is about being a person with a heart and a brain that doesn't only live inside your pocket book.
