I have the answer to this as I live in the land of the "Free Range Chicken".  I have studied the subject of the Chicken taking it's self for a walk as well as llamas, pigs, cows, cats, dogs, horses, rats, gigantic and alien-like bugs... two parrots, a canary, 28 turtles and non-venomous snakes...

They cross the road because "THE OVER" is there.

I dream of a world where a chicken can can cross the road without his motives being questioned..

Emily Dickinson:
Because it could not stop for death.

Epicurus:
For fun.

Ralph Waldo Emerson:
It didn't cross the road; it transcended it.

Johann von Goethe:
The eternal hen-principle made it do it.

Ernest Hemingway:
To die. In the rain.

Werner Heisenberg:
We are not sure which side of the road the chicken was on, but it was moving very fast.

Jack Nicholson:
'Cause it (censored) wanted to. That's the (censored) reason.

Pyrrho the Skeptic:
What road?

The Sphinx:
You tell me.

Henry David Thoreau:
To live deliberately ... and suck all the marrow out of life.

Howard Cosell:
It may very well have been one of the most astonishing events to grace the annals of history. An historic, unprecedented avian biped with the temerity to attempt such an herculean achievement formerly relegated to homo sapien pedestrians is truly a remarkable occurrence.
