We have a ewe that started last night separating herself from the other ewes, she won't come eat her grain, which is unusual for her. Whenever I checked her today, she was a little away from the others. She is alert and will run around when startled, looks OK, but is acting the way a ewe does when ready to deliver lambs. The only strange part is that she has not been bred, unless one of the rams has learned to do the deed through a box wire fence! Anybody have any other ideas why she would act this way? Can sheep have a "false" pregnancy, the way dogs can?
