ewe started the normal pawing the ground, lying down, getting up etc at about 2pm today. I clocked her earlier at 10am with "that look" about her and reckoned she would lamb today. Took herself off to a quiet spot in the field at about 4pm. Been pawing, lying down, straining since then. Got her into a pen an hour ago and left her be. Just been out to check her. No progress. Had a gentle feel inside up to end of my fingers and nothing to feel, but she was quite tight. Lots of clear mucus with no nasty smell. Have left her in peace but should I be worried after 5 hours of "i am going to lamb"??
