Morgan Spurlock did a sequel to Super Size Me (Super Size Me 2: Holy Chicken) and it's a great deep dive into the chicken industry. He describes the growth of chickens that this article touches upon, but you can see the size differences with the chickens he raises. He buys the broilers as chicks and raises them for a few weeks until slaughter, touching upon "cage free", "free range" and all the other buzzwords. Most surprising to me was just a few minutes where they talk about the chickens becoming so big, so fast, that a few dozen die before slaughter from heart attacks, broken legs, or just suffocation from their sheer size. https://en.wikipedia.org/wiki/Super_Size_Me_2:_Holy_Chicken https://en.wikipedia.org/wiki/Super_Size_Me_2:_Holy_Chicken!
