Back when I was a kid, we had chickens and ducks among the menagerie on our hobby farm.
The rooster and the drake (that's the boy version of a duck, for you city-slickers) did not get along. Sometimes the rooster would chase the drake around the barnyard, sometimes the drake would chase the rooster.
One day the drake managed to catch the rooster by the tailfeathers. The rooster was flapping its wings for all it was worth as the drake dug in with both heels. Next thing you know, the feathers let loose, the rooster went shooting over the chicken coop, and the drake rolled head-over-heels backward.
Too bad there wasn't YouTube back then.
