your serfs were compelled to leave their ewes in your enclosure overnight

No, no, no, Dr. Bill. You're letting your hyperbolic imagination run away with you again. I am not growing rye in my enclosure. I am not growing barleycorn in my enclosure. Manurage! Manurage is what it's all about. Can you say manurage? Sure you can. I tell them to pasture the sheep in the barleycorn field when I want them (the sheep) to fertilize the barleycorn field and in the rye field when I want them to fertilize the rye field.
