We all think we know about farm animals - that sheep are stupid, pigs are smart and that cows lie down when it is going to rain. But there's a lot more to them than that. In this series we're bringing together some of the country's best farms to create one sun-dappled ideal where we will test animal intelligence, discover unlikely relationships and uncover a side of farm animals you've never seen before.
It is harvest season. We follow a litter of piglets from birth as they grow up in the Brecon Beacons. We test the theory that every piglet always returns to the same teat to suckle, show that pigs love mud to keep cool because they have practically no sweat glands, and we show how intelligent they are with a series of puzzles. We also reveal that they are masters at the art of deception. Pigs tell porkies! Along the way we meet a pair of kunekune pigs raised as domestic pets in the heart of London. We visit a farm that uses llamas to guard its sheep and meet a pet rabbit with a remarkable identity crisis. Show less
