The Chicken Run just cracks me up. Particularly when my bantam Buff Brahma roo, Charlie, takes off and runs like a small, feathered T-Rex. Because of his build, it's so much more evident that chickens descended from dinosaurs.
Watching hens run, from behind them, just simply generates giggles. And if she's after something, not just trying to get somewhere ahead of other flock-mates, that head down, beak forward and level with the mid-line of her body, so determined, I think to myself, "Wow, they could pop car tires if they wanted to!"
Makes ya think, don't it??
