Daffy Duck, outraged by the low prize for ducks at the National Poultry Show, disguises himself as a rooster to win the $5,000 prize. However, his plan goes awry when he is mistaken for a chicken and taken home by Henery Hawk. Trapped in a chicken-hawk's house, Daffy's attempts to prove he is a duck only lead to chaos. Eventually escaping, he rushes back to the contest but loses both the rooster and duck prizes to Henery's father and Henery himself.
Production notes
You Were Never Duckier marked the start of a direction change for Daffy, from a screwball, to a greedy, self-centered one (though, according to commentary by Eric Goldberg on the Looney Tunes Golden CollectionDVD [fifth volume], this cartoon showed Daffy as being both a greedy, self-centered character and a screwball one). This cartoon was also the penultimate Henery Hawk cartoon to not be directed by Robert McKimson, and one of only three to be directed by creator Chuck Jones (after The Squawkin' Hawk and followed by The Scarlet Pumpernickel).
