Before they even left the chicken coop, three of them decided to stay behind to knit beak-warmers.
On the way to the road, half of the chickens decided to go for ice cream instead.
When the ones that were left got to the road, two thirds of them got frightened and went back to the coop.
Although brave, the ones that were left were also quite stupid. Five of them forgot to look both ways and got run over by a fox who was speeding by in his new SUV.
In the end, only one chicken successfully crossed the road.
How many chickens originally had decided to cross the road?
