Jacobs!!! Ewes require less supplement feed during times of increased nutritional need and lamb easily, usually with no assistance. The lambs are up and nursing vigorously without help. Jacob ewes are included in commercial flock in England due to their hardiness, ease of lambing, strong mothering instincts. Both rams and ewes are easily kept and have a resistance to parasites and foot problems. The fleece is soft and open and light in grease, making it highly sought after by handspinners.
