Each square was sold for $2. Once all of the squares were sold, it was time for the chicken. The entire point of the game is to wait for the chicken to shit on a square. Whoever owns that square wins half the money collected. This sounds simple enough except that the chicken wouldn't shit. Imagine a large group of adults, standing around the perimeter of the box, literally trying to scare the shit out of the chicken.
In the end, the stunt chicken was brought in. She was well prepared for her role; she promptly shit on square 8 and then went back to doing whatever chickens do in their leisure time.
