Chicken smuggling: a football fan's guide

Much credit to the Blackburn fan who smuggled a chicken into Ewood Park to protest the side's owners, Venky's. But when most grounds check any kind of bag for booze, weapons or, God forbid, water, the question is – like when Inter fans smuggled a Vespa into the San Siro in 2001 – how did they do that?

Presuming stewards were checking bags and that the "chicken up the jumper" method is too clucking scratchy, there can be only one answer. Someone borrowed Mario Balotelli's famous hat.
