Lambing Live returns. This time Kate Humble and Adam Henson put on their wellies and head to Scotland to test their shepherding skills. After a devastating spring in 2013 and a very wet and windy winter, the life-and-death drama of lambing is more of a gamble than ever before. This introduces the new family of farmers, the Dykes, and the very first lambs. Over the past six months, Kate's been learning that having a few sheep at home is very different to managing over a thousand in the hills of the Borders. And Adam's been travelling the UK and beyond to explore the secret life of sheep. How many lambs will be born? How many will survive? Follow their stories over the next four nights.
