I'm guessing the rotary parlor isn't operational 24 hours. 550 goats a day, at 40 per round is about 14 rounds, so possibly 2 rounds per hour. Can you really milk 550 goats in 8 hours?
Actually, the only thing that wasn't stolen at the Louvre's Apollo Gallery is the Regent Diamond, figure no one would take it because something to do with a curse.
