The official Due dates begin on Monday, but I still walk through the sheep flock a couple times a day. I have never had a ewe deliver early. They usually start right on the day or after. I still get a little excited every time I walk out there, hoping to spot or hear some new little lambs. There are quite a few ewes that look like they are ready. We have a barn and pens to clean and get ready yet, so they can hold off a couple more days.
