Chicken Little (1943)

Directed by Clyde Geronimi

It's a peaceful day at the local poultry farm until Foxy Loxy happens along intent on a chicken dinner. He takes the advice of a book on psychology by striking "the least intelligent" first and convinces dim witted Chicken Little the sky is falling. Chicken Little spreads the word but when head man Cocky Locky proves the story to be false, Foxy Loxy spreads rumors that Cocky Locky isn't the smart chicken he appears to be, which leads to the ultimate undoing of the chickens at the hands of Foxy Loxy.
