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?

If so, what’s the ‘happier’ alternative – and do carnivores like Chris care enough to pay the price for that, or does a love of meat ultimately trump ethics?

Chris battles with his conscience, and finds the answer hard to stomach.
