I believe that this is somehow luck related game but if you have a rare breed kind of roosters in your lawn then the luck is mostly in favor with you. I know it's illegal in some places mostly in the crowded city but this kind of gambling is very famous to the elders that the betting amount sometimes would exceeded to $1000 or more. I don't think this kind of gambling would happen within the city, it must be somewhere far from it or an underground gambling lair.
