After her feats of math and science derring-do, Chirpy is the talk of the coop. So when the chicks face a new problem—Clucky greedily chomping down on all the chow—they turn to their Great Mathemachicken for a solution. Wandering off to think, she meets Quackers, a very curious duck, who has a lot of his own questions. Unfortunately, Chirpy doesn’t have answers. But she knows the best place to find them—school! So the pair hops on the bus to do some investigation, learning about reading and pizza, tally marks and fractions. And it turns out, fractions are yummy . . .  and may be the answer to the chickens’ coop conundrum.
