The fast shift toward uncaged hens is a sign of Americans’ increasing concern about animals, even ones known more for clucking than cuteness. But it also amounts to one of the animal advocacy movement’s biggest victories in decades – one brought about by ballot measures, campaigns against companies, foodie culture and, above all, the power of the Internet.
Why can't this mean that cage free eggs became more economic than caged ones?
Nowadays they put a bunch of chickens in a too small area, shave their beaks off so they don't fight, and probably use automated systems to collect the eggs that don't need to be in a limited range. Now, without iron bars, you can fit more chickens in a smaller area, and the chickens are overall healthier and produce more thanks to being able to walk around.
