We’ve heard about the potential problems around chicken welfare. But how does that square with their impact on the environment?

Dr Chris van Tulleken finds out what it takes to produce the most eco-friendly chicken meat possible. And makes a devastating discovery. Welfare concerns, and environmental credentials, often pull in OPPOSITE directions. Does he want to eat the happiest birds, or the ones kindest to the planet?

Halfway through his poultry quest, Chris remains massively conflicted: he loves chicken, but some of what he’s discovered makes him question how much he eats it. Will he still be able to look at it the same way as he goes deeper down the rabbit hole? And more importantly, should he keep serving it up to the family?
