I have eight chicken of mutated breeding. There is a road which they cross daily to get to the other field. In the field is a water source running underground. It's naturally boggy and there is an abundance of worms, Diptera and other Arthropoda to feast on.
There is only one reason why my chickens cross the road. There is no debate, no philosophical musing, no writing wit on Medium.
They cross to eat, just like humans do to get to that flaming pizza parlour across the road. And if they get run over by a Hyundai on the way, they'll know nothing about it, because their tongues, like the beaks of chickens, are already noshing.
FACT.
Cheers.
