In addition to our Lamancha goats, we have two Katahdin sheep that each had twins last weekend. We are trying to evaluate whether the lambs are getting enough milk. The ewe's udders don't look or feel at all like the dairy goats' udders. But maybe that's normal for animals that were not bred to be milked? Actually we also worried about the Lamancha's kids getting enough milk, since this was our first experience with kidding. But they have come along fine.
