It is the featherless red appendage on top of the head.

The red things hanging from the bottom of the head behind the beak are the wattles.

The white, red or purple things without feathers just to the rear and below the eyes are earlobes.

It's that thing my rooster Henry keeps in his back pocket, just like Fonzie.

Which is really funny because, well, Henry Winkler!
