Willard Tweedy is the (former) secondary antagonist of Chicken Run. He is Mrs. Tweedy's husband and right-hand man.
Personality
Mr. Tweedy always obeyed Mrs. Tweedy's orders, no matter how unreasonable or foolish they may seem.
Mr. Tweedy kind of acts like a good guy (as he is afraid of his wife).
At the end of the film, as the Tweedys' chicken pie business had gone bankrupt, Mr. Tweedy gets back at Mrs. Tweedy by pushing a door down on her.
Mr. Tweedy's attitude and behavior is similar to Whitey's (one of The Toad's henchrats from Flushed Away).
