From The Lost Media Wiki
Why It Was Cancelled The first film received mixed to negative reviews from critics and audiences, despite being a box office success, so Disney decided not to make the sequel, and John Lasseter banned all future sequels after his appointment to CEO of Disney in 2006. Result Chicken Little 2: Mission To Mars was permanently cancelled. Some of the elements of the sequel were used in the game Chicken Little: Ace In Action, and the game serves as a sequel to the film. Aside from that, Chicken Little is a stand-alone film.
