Fowler the Rooster is a supporting character in Chicken Run to be a mascot of the Royal Air Force. (Specifically the 644 Squadron, Poultry Division).
He is a grayish-blue-colored rooster and also sensible to clothing, so when he exclaims "operation coming up", one of the chickens hide him with a sock and long minutes after, he falls to "snooze". Fowler mostly wears a medal with a white scarf.
Fowler also carries a baton.
Fowler always talks about his days at the RAF.
Though he came off as grouchy and cruel, he is in reality a very kind rooster who also wishes for the chickens to have a better life.
When Fowler first met Rocky, he showed discontent and called Rocky a "yank". He especially hated having to share his bunk with him, a feeling that Rocky shared. But after Rocky saved Ginger from the pie machine, Fowler started to respect him and even let him take the entire bunk.
Ginger entrusted Fowler to fly the plane that took the Chickens out of the farm. Fowler was initially reluctant, but upon encouragement from Ginger and Bunty, he agreed.
