What are the housing needs of sheep?
To some extent this depends on breed. Primitive breeds need little, if any housing, other than perhaps a bit of shade from the sun when it’s hot, and a windbreak for protection from the worst winter winds. Modern breeds may need overhead protection from rain and snow. Few sheep really need barns. They are generally more for the shepherd’s comfort than the sheep’s. If we were doing it over again, we probably wouldn’t build a barn for the sheep, though we would definitely build a barn for the hay!
