We were given an old pet ewe by the farmer across the valley, to be a "Nanny" to our tegs and live out her life on our quieter farm. She was sharing a field with a ewe that had scanned empty, although the ram had had to stay in longer than usual with the ewes that year. My daughter spotted her running up and down along the top of the field, every now and again stopping to look down at the dry ditch and bleat, then look back at my daughter (shades of Lassie Come Home). The other ewe was licking off twins in the ditch.
