Trivia

If viewed closely during the film's final shot, an imposter chicken in the form of the nefarious penguin Feathers McGraw from the second Wallace & Gromit short, "Wrong Trousers," can be seen.

Julia Sawalha and Mel Gibson did not reprise their respective roles as Ginger and Rocky. Gibson was not cast due to his past controversies, while Sawalha was told her voice now sounds "too old", a decision she criticized as ageist. Timothy Spall (Nick) and Phil Daniels (Fetcher) were also recast, as well as Benjamin Whitrow (Fowler), who passed away in 2017. However, Jane Horrocks, Imelda Staunton, Lynn Ferguson, and Miranda Richardson did return as Babs, Bunty, Mac, and Mrs. Tweedy.

To prevent the chicken puppets from having too much of a sheen on camera, each one had finely sifted icing sugar puffed onto its surface, creating an even matte effect.

Crushed walnut shells were used to create road surfaces, while the soil texture on the chicken village set was made from recycled fallen leaves from a leylandii tree outside the studio.

The film contains around 1,400 shots in total, only 28 of which are fully computer generated. The longest shot is the opening pan across Chicken Island, which is 784 frames, or 32.67 seconds. It took 80 working days to shoot the animation.
