Fan Casting Chicken Run (2008)

A flock of chickens live on an egg farm set up like a prisoner-of-war camp. The farm is run by the cruel Mrs. Tweedy and her oafish husband Mr. Tweedy, who kill and eat any chicken that is no longer able to lay eggs. The chickens try to escape frequently, but are always caught. Frustrated at the minuscule and declining profits that the farm generates, Mrs. Tweedy gets an idea of converting the farm to automated production and having a machine turn the chickens into meat pies. Mr. Tweedy suspects the chickens' sapience and wonders if they are plotting, but Mrs. Tweedy dismisses his theories.

One day, the chickens' leader, Ginger, witnesses an American rooster named Rocky Rhodes crash-land in the farm's coop; the chickens put his damaged wing in a cast and hide him from the Tweedys. Interested in Rocky's apparent flying abilities, Ginger begs him to help teach her and the chickens to fly. Rocky gives them training lessons while Mr. Tweedy builds the pie machine. Later that night, Rocky holds a dance party when his wing is healed; Ginger insists he demonstrates flying the next day, but Mr. Tweedy finishes the pie machine and puts Ginger in it for a test run. Rocky saves her and inadvertently sabotages the machine, buying them time to warn the chickens and plan an escape from the farm.
