The chickens live in a farm run by the Tweedys. They try to escape, but are always caught. Frustrated at the minuscule and declining profits that the farm generates, Mrs. Tweedy conceives an idea of converting the farm to automated production and having a pie machine in the barn in order to turn the chickens into meat pies. One day, Ginger, the leader of the chickens, observes a rooster named Rocky crash-landing into the farm after being shot from a circus cannon. Ginger and the chickens hide him from the Tweedys. Ginger, interested in Rocky’s flying abilities, begs him to help teach her and the chickens to fly. Rocky gives them training lessons in the meantime while Mr. Tweedy builds the pie machine. Later, Rocky holds a party and Ginger insists he show them to fly the next day, but Mr. Tweedy finishes making the pie machine and puts Ginger in it for a test run. Rocky saves Ginger, giving them time to warn the others of the Tweedys’ plan to make them into pies and only a short time for their escape.
The next day, Ginger finds Rocky has fled, leaving behind part of a poster that shows him to be a stunt rooster, shot out of a cannon from a circus and unable to fly himself, depressing Ginger and the others. Fowler the rooster tries to cheer them up by telling stories of being an RAF (Royal Air Force) division mascot, leading Ginger the idea of creating a plane to flee from the farm. The chickens assemble parts for the plane as Mrs. Tweedy insists Mr. Tweedy gather all the chickens to put into the machine, but when he comes in, the chickens attack Mr. Tweedy, leaving him bound and gagged, as they finish the plane. Rocky returns and joins them, but while taking off, Mrs. Tweedy chases them and climbs up a strand of lights while Ginger races to sever it, managing to cut the strand, sending Mrs. Tweedy into the pie machine, which causes it to explode. The chickens continue their flight to freedom, and find an island where they enjoy their freedom, and Ginger and Rocky start a relationship.
