It is a thankless task Andrew, we still have some sheep in East Yorks, but nowhere near as many (thousands!) as we had 30 years ago. I am not directly involved, but used to rig up lights and heaters for the lads that were. A lot gave up after the last F&M outbreak which clamped down on movement, and although we never actually got the disease, a lot of sheep which should have been moved to drier pasture got foot rot, and had to be destroyed, but no compensation!. Just down the road from me, at Kilham, was the biggest sheep sale in the north, which went back to medieval times, all gone now of course. Keep up the good work, and best of luck with them! Very underrated as food, I always loved mutton stew when I was a kid!
