Of Rice and Hen(1953)

Overview:

Miss Prissy, the slow-witted hen, sets out to land a husband - Foghorn Leghorn, and Barnyard Dog is willing to help her by dressing as a rooster to "rival" Foghorn Leghorn's non-existent affections and make him jealous so that he'll marry Prissy without thinking. Foghorn Leghorn falls for the scheme - hook, line, and sinker.
