Watching chickens helps us understand human motivations and interactions, which is doubtless why so many words and phrases in common parlance are redolent of the hen yard: “pecking order”, “cockiness”, “ruffling somebody’s feathers”, “taking somebody under your wing”, “fussing like a mother hen”, “strutting”, a “bantamweight fighter”, “clipping someone’s wings”, “beady eyes”, “chicks”, “to crow”, “to flock”, “get in a flap”, “coming home to roost”, “don’t count your chickens before they’re hatched”, “nest eggs” and “preening”.
