Manchester, England-based animation studio Cosgrove Hall, known for its stop-motion production on series such as “Brambly Hedge” and “The Animal Shelf,” is launching production on a new, 26-part, drawn 2D animated series called “Foxbusters.” The show is about a group of renegade chickens that challenge the process of natural selection and try not to get eaten by foxes. David Freedman and Alan Gilbey are writing scripts. The ITV Network Centre has commissioned 11 episodes for debut in September 1999. “Foxbusters” will be distributed by Cosgrove’s sister company, ITEL.
