Watch a Robot 'Hen' Adopt a Flock of Chicks

I don't want to tell these baby chickens how to live, but they're going about their business all wrong. The cylindrical robot in their pen looks nothing like a hen, and it makes decidedly un-hen-like beeps, yet the chicks trail it obsessively, as if it's their mother. Where the PoulBot goes, so too go the yellow little fluffs. Beep beep beep, says the robot. Chirp chirp chirp, say the chicks.
