I have just watched a programme called "Living with a size Zero". In a nut shell super skinny birds who either puke up their scoff or just don't eat enough. I've never been much of a fan of uber skinny birds, but it got me thinking. Other than being walking coat hangers that look like 11 year old boys in the Fashion Industry what use are size zero birds? It's not as if they will swallow or even eat sausage!
