Mike noticed it first when we were getting ready to do the morning chores, Sapphire was acting unusual. She was hanging away from the main herd, had her tail raised a bit, and kept sniffing the ground. All tell-tail signs that she was in labor.
The day had turned blustery during feeding so we moved Sapphire away from the main group and put her into the barnyard. She acted ravenous, and could not stop eating grass even though it was obvious that she was in the first stages of labor. (It was breakfast time, and she was hungry).
We opened up the barn for her to go inside out of the rain if she wanted and fluffed up several armloads of hay into the manger inside. About an hour later she moved under cover and ate her fill of the sweet hay while continuing with contractions.
By mid-day she had delivered Violet, a 78 lb. heifer.
Once she figured out the legs, she stood up and started walking until she was steady enough to nurse.
