Henery Hawk is a chickenhawk who, as the cartoon begins, learns from his father that his destiny is to eat chickens. Henery doesn't have any idea what a chicken is, but he goes off looking anyway. He finds a farm and an actual chicken, Foghorn Leghorn himself. Foghorn takes advantage of Henery's naivete by telling him that Foghorn's enemy, Barnyard Dog, is actually a chicken. Hijinks ensue as Henery chases after Foghorn and Barnyard in search of something to eat.
Foghorn Leghorn's debut. This cartoon actually is focused on Henery, but Foghorn became the star, and future cartoons in this series would focus on him.
- Art Initiates Life: At one point, Henery gets the Dog to come out of his house to walk into a trap by drawing a doorbell on the doghouse and then ringing it.
- Banana Peel: Part of the elaborate trap that Henery constructs to catch Barnyard Dog.
- Borrowed Catchphrase: Ends with Henery dragging Foggy, Barnyard Dawg and a horse behind him.Henery: One of these things, I say, one of these things has got to be a chicken!
- Breakout Character: Foghorn became the star with the second cartoon, "Crowing Pains".
- Comedic Spanking: Foghorn likes to do this to Barnyard Dog.
- Early Installment Weirdness: Foghorn has three toes instead of two and four tail feathers. By the second cartoon, Foghorn had two toes, and three tail feathers (though some cartoons depict him with four). Foghorn sounds more like Yosemite Sam in this short. Foghorn makes realistic chicken squawking noises when Barnyard Dog attacks him, something that rarely happened later. Also, in this short Henery Hawk is the star.
- From the Mouths of Babes: When it looks like Henery's father is about to give him The Talk, Henery responds, "Okay, pop. What you wanna know?"
- Let's You and Him Fight: In a pattern that would be repeated in the series, Foghorn convinces a naïve Henery that the Barnyard Dog is a chicken so Henery can go after the dog and leave him alone.
- Pint-Sized Powerhouse: The short ends with tiny little Henery dragging Foghorn, Barnyard Dog, and a horse.
- Running Gag: Barnyard Dog chasing after something, only to be brought to a sudden violent halt by his leash.
- Shout-Out: Henery's line "So round, so firm, so fully packed" when admiring the Barnyard Dog's tail was the slogan for Lucky Strike cigarettes.
- The Talk: Parodied. Henery's father gives a talk that sounds like he's going to explain the facts of life ("Well Henery, you're a big boy now"), only for him to tell Henery that he's destined to eat chickens.
