Not that many sheep around. but one has to remember that no one leaves their breeding flocks up here for the winter. Unless the farmer has quite extensive pasturage flat round the farm, which is not generally available in hill country, the sheep go on their ‘hols’ to Pembrokeshire for the late autumn and early winter to eat someone else’s grass or fodder crops whilst they are carrying their lambs. Most of S Pembs is arable farming, sheep coming in are a cash sideline between crops. The sheep are shipped home before they start to lamb which keeps their home pastures in the best possible condition. Producing milk for lambs requires good nutrition, not worn out over eaten grass, and hay, beyond the limited quantity that can be made on a hill farm, is bloody expensive to buy. Which explains why at some times of year there are either no sheep or lots of them.
