Well, sure, chickens have been "doing their chicken thing" for thousands of years.
OTOH, "their chicken thing" that they do on their own contains a very high component of dying young and sometimes messily, from various diseases and disorders and from predators.
If one doesn't mind losing more chickens, and losing them younger and sicker, then sure, just kick 'em out there and don't worry and let them be chickens.
However, those who have the time and energy and interest to take a little more active care of them will have larger and more-productive and longer-lived flocks.
Anyhow, plenty of old-time farmers DID pay very close attention to their livestock and take good individual care of 'em. They tended to be the farmers whose animals did better, on the whole
