Sheep - The Cam, Fen Ditton

Certainly the first sheep to have been photographed this year, and probably the last.   I don't know the breed but will spend more time trying to identify it.   I imagine they are bred for wool, and perhaps meat, and the lambs have very woolly legs and the heads of the adults are woolly and rather attractive and characterful, for sheep!   I wonder how rare a breed it might be.   The sheep are in the field adjacent to this well maintained garden.
