All sheep are different but I've seen all of these signs of impending contractions: going off feed, standing away from the flock, lying down with one leg out to brace themselves, lifting their head up neck stretched back and moaning or grinding their teeth, pawing at the ground circling making a nest, tail raised, vulva area very swollen and red, literally looking like their whole body is a single muscle pushing the baby out. Hope this helps!
