This happens occasionally to one of our first-timers and we put the ewe in a home-made adopter - long vertical slot with bar at the top for her neck, spaces at the side so the lambs can get round in front of her nose, bucket on one side, pile of hay on the other, fits across the corner of the pen. In a day or so she'll calm down and in the meantime the lambs can suckle and don't get kicked. Yes, the breed has survived for many centuries but you don't know how many over-enthusiastic first-timers pawed their lambs and damaged their ribs, or worse, in the past.
