Fear of chickens (Alektorophobia)

Chickens are delicious, not terrifying. Why would anyone be afraid of a bird that humans breed en masse, dismember, deep fry and serve in buckets? It has been hypothesized that chickens are descended from dinosaurs. A genetically engineered Tyrannosaurus Rex on a rampage is something to be afraid of, if they existed. But they don't. Chickens exist, and they're just giant flightless nuggets.
