This year is the 50th anniversary of the Rare Breed Survival Trust, a charity founded by Adam’s father, Joe Henson, to reverse the decline of rare breed numbers in the UK. To mark this date, we visit Adam’s farm to see how he’s taken on the mantle. With summer temperatures rising, Adam welcomes a shearing gang on site to remove the coats of his commercial sheep, before learning more about their ancient cousins. We catch up with an Exmoor pony stallion, Willow Warbler, to find out if he has been welcomed by the mares on the farm and sired any foals. Lexi, a Suffolk punch horse, goes for a pregnancy scan. A Gloucester bull is prepared for a day at a country show with a thorough head-to-tail wash, and Adam is visited by the chief executive of the British Pig Association for a very special moment.
