So we’ve got a comprehensive overview of the chicken planet we live on... Do we still want to eat it? And if NOT, what are the alternatives? Dr Chris van Tulleken wrestles with the final dilemma: slaughter. Could he bring himself to dispatch an animal himself? Is he happy supporting an industry which kills animals in his name? And if not, what could he eat instead? We explore the rise of the alternative protein industry – plant-based meat alternatives, lab-grown meat, or most shocking of all...

We're a planet addicted to chicken - and our appetites fuel a massive global industry... but is it one we should support? As Chris wrestles with how he personally feels about this weird and wonderful bird, he decides to take a look at the business as a whole: a global industry that's cited by some as a shining example of a super-efficient food production system, one that could help drive food security around the world.

Chris has learned how to make better chicken choices, and what those choices really mean. So why is he STILL eating CRAP?

We eat chicken. A LOT of it. We might love the taste, but what about how we're treating those birds? After witnessing first-hand the reality of indoor chicken farming - how most of the chicken we eat is raised - Dr Chris van Tulleken wants to know: are the birds happy enough, or is our method of rearing cheap chicken actually cruel?

So we started farming this bird called chicken, and it spread around the world. But what does it actually TAKE to feed us the amount of chicken we want to consume? 100 years ago this was a scrawny, egg-laying bird, only good for a stew once her eggs ran out – no one ate chicken meat. Fast forward to today and it’s the most consumed protein on the planet. How did we come to eat it in the first place, and what are the consequences of producing chicken meat on the vast, industrial scales we now...
