Rooing
In some primitive sheep (for example in many Shetlands), there is a natural break in the growth of the wool in spring. By late spring this causes the fleece to begin to peel away from the body, and it may then be plucked by hand without cutting – this is known as rooing. Individual sheep may reach this stage at slightly different times.
