An Extraordinary Egg 1st edition

Illus. in full color. While taking a walk, three frogs discover what they believe to be a chicken egg and eagerly wait for it to hatch. When a scaly, four-legged creature with a long snoutful of teeth emerges a few days later, the frogs are still convinced it's a chicken and are thrilled to have a new friend. Soon the frogs and "chicken" are inseparable, at least until the day "chicken" finds and returns to her mother...an enormous "hen" who looks suspiciously like an alligator!
