Don't call the midwife!

My smallholder friend has two sheep, Schwartz and Weiss. They were not intended for breeding but for the other purpose. However, without her realising it, nature took its course.
Three days ago the ewe, Weiss, was found to have delivered, unaided, three healthy little Schwartzes. My friend, who is a trained midwife, was taken completely by surprise and was not even at home for the birth.
