Mr. Ruhle gives the class the task of caring for Giblets, his pet chicken. However, Giblets "flies the coop" and the class decides to get a new Rhode Island Red to replace Giblets. Naturally, they decide to hatch one from an egg. They learn on their trip that both a male and female chicken are needed to produce a chicken—though it is never explained how, (being a children's show). At the last minute Giblets returns, and Ms. Frizzle cracks, "I guess he who flies the coop can always fly back again."
