The conceptual if not the literal ancestors of most of Britain’s chickens were smuggled into the country disguised as Easter eggs. Their bootlegger was Antony Fisher, a former RAF pilot who had been advised by Friedrich Hayek to make his mark not by getting into politics but by nudging public opinion from the helm of a research institute. Fisher went in search of funds. On a trip to the US, he saw fifteen thousand supersized chickens packed into a single poultry house. He wrapped two dozen fertilised eggs in foil and stashed them in his hand luggage for the return trip.
