    The road being frictionless is irrelevant unless it’s also in a vacuum.

    Chickens are not very good fliers, sure, but even this spherical chicken could probably manage a short flight to whichever side of the road it pleased.

      If we assume the ground is frictionless, I’d assume we’re assuming no air resistance, just to make it easy

        Air resistance would make flight harder, though, not easier, wouldn’t it…?

        As I understand it wings work by Bernoulli’s principle, which is an air pressure / conservation of energy thing, so it should still work in a frictionless atmosphere…

        Then again, we’re talking chickens here (and spherical ones at that), which aren’t particularly renowned for their aerodynamics and wing efficiency, so maybe they would need to be able to push on the air to generate lift…
