We reach the third paddock of our journey through Warrawindi Farms, in South Australia’s Coonawarra region, to find a struggling ewe, the tiny hooves of her first lamb visible. Ben Brooksby, a sixth-generation farmer and the son-in-law of the farm’s owners, Alison and David Galpin, approaches to help. Three minutes later, twins: one lost, the other gently licked by its mother as its faint heartbeat strengthens in the early minutes of life.
