Chickens, like all birds, evolved from the only surviving line of the dinosaurs. They did not just pop into existence out of a vaccuum. Everything on Earth today has been evolving for hundreds of millions of years, just under a variety of species, genera, families, etc.I suggest wile your reading up in poultry nutrition you read about the "evaluation" of them also...
Millions of years? That's a good one, try only around 8,000 to 10,000 years.
Man created them by breeding different types of Jungle Fowl.
There was no Gallus Gallus Domesticus running around millions of years ago.
Again, I don't see how a few decades of evaluations of formulated chicken feed negates the millions of years of evolution and survival and adaptation to living in the wild that got them to modern times. The scientific method is a great invention, but humans are at their most vulnerable when we become so arrogant as to think we're more clever than nature.
