Do you know to play a game of tag? When someone have to catch the others? Well, this is something very similar.
Unfortunately, the one chasing is a rooster—fastened to a pole. His ‘target’ is a second rooster, belted to the same pole but suspended one foot above the ground. While there is no way of actually catching each other, they will keep spinning around and around.
It’s a little bit like a carrot on a stick you will chase it. As long as they don’t get dizzy, they cannot help chasing each other.
