Corrected entry: The second time the plane comes down the lane (after having to turn around), it would have arrived at Ginger and Rocky long before it actually does.
Corrected entry: There are several points throughout the film where you can see a fence go right through the farm. This is proved by the fact that there are huts on either side of the fence.
Corrected entry: When they are all lined up, Ginger hands Mac the plan for the escape. Mac wrongly reads it and says about going under the fence, then Ginger turns it. Then Mac realises they go over the fence. But Ginger only turned it 90 degrees. If Mac was to read the plan properly, it should have been 180 degrees.
Corrected entry: After take-off, the chickens fly the 'crate' away from the farmhouse, and even just over the Mrs Tweedy's Chicken Pies sign, yet Mrs Tweedy still manages to enter the farm house via the round window in the farmhouse, and this would have only been possible if a number of about turns were made, which we would have noticed during the action with the axe, etc.
Corrected entry: The film takes place in the 1950s, but the song "Flip Flop and Fly" by the Blues Brothers that the chickens play at the dance was not written until 1978.
Corrected entry: After Rocky collides into the flower bed at the start, the chickens help him in and if you look closely at his chest you can see a faint thumbprint on it.
Corrected entry: When Nick and Fetcher bring the radio into the pen, it is about as tall as Rocky. Yet later, when he is on the tricycle, it is small enough to put in a little basket. How is this possible?
