This is a video of a Brahma chicken. It is very large. We haven’t done any research on this breed of chicken, but this video suggests that they can grow up to 150 pounds and up to 4 feet tall. They are carnivores and have been known to eat small children.
In olden times some brave cowboys put saddles on them and rode them around to impress women.
I, for one, welcome our new giant chicken overlords.
