There's a new legend in town! New Zealander, Carl Scott is at this very moment, sitting alone in a tiny cage next to a highway, and he plans to stay there for a whole month!
The space he's living in for the next month is less than two metres across, 130cm high (he can't even stand up!) and even includes his toilet. Yet Carl would be the first to tell you that despite these cramped conditions he's still got it way better than the average chook (let's call her Betty).
To start with, Betty doesn't have her own cage; she has to share it with up to 5 other birds, with less than the space of an A4 piece of paper for each to live in . She can't even flap her wings!
Betty's cage is one of thousands of cages, stacked in rows - up to four cages high. Living in the bottom row, she is showered with waste from hens locked in cages above hers.
Betty has lost many of the feathers that would keep her warm from constantly rubbing against the wire of the cage. If Betty isn't living in chronic pain from an untreated broken bone, then stats suggest that at least one of her cagemates is. 
For virtually her entire life, she has been locked in this tiny cage in a windowless shed. The short time before she was put in this cage was no more pleasant. During that time the tip of her beak was sliced off with a hot iron, without any pain relief.
Even if Betty survives life in this miserable cage, her only 'reward' for producing eggs will be death. When she no longer lays enough eggs to be 'profitable', she will be trucked off to slaughter with her cage-mates (before her second birthday), without ever knowing the simple joys of dustbathing, perching or building her own nest.
There is absolutely no doubt that chickens in battery cages endure a life of hell. None of us would want to trade places with them. Which makes Carl's demonstration all the more heroic. Carl, you're a legend!
Do you think you could spend a month in a cage for the cause?
