Kate Humble and Adam Henson bring you the latest live from the lambing sheds in Wales. With 300 expectant ewes they've got their work cut out. Kate discovers that pregnant sheep get ultrasounds too, while Adam looks at the history of sheep farming, from our most ancient breeds to the modern cross-bred 'mule'.
Plus news on all our lambs, as well as the possibility of a birth. Kate will have to test her shepherding skills first hand.
