 The industry she sparked into existence is all around us. Every year in the UK, we produce around a billion chickens. And yet they seem to be invisible. I've never even seen one of the 2,000 to 3,000 farms that produce them, mostly out of sight, mostly in sheds. I want to see for myself what the chicken industry looks like today. So I've come to Gloucestershire to meet Charles. Do you get along with your neighbours? Oh, yeah. I've got five vegans live over there.
