We came home this evening to find two rams grazing on one of our pastures. We had seen them on the highway the other day. Apparently the cattle guard didn't bother them, because they would have had to cross it to get on our place. Their fleece looks pretty ratty and they don't look to be in good shape. They have ear tags. We haven't approached them to see if the tags contain any useful information but I highly doubt it. Is there any way besides word-of-mouth to locate the owners? Are sheep usually tattoed or something?
