Not that unusual to find odd dead sheep/cattle near to hill fences in this country where lightening has struck the fence further up..
Not seen a report of what the plan is yet - move or leave them. Very unusual event!
finnbear Could be a local hunter has tooled himself up with a Death-Ray or fixed a chain gun to his quad. But my money's on lightning.
I read that the plan was to test a sample number of them for CWD but otherwise they would be left in place. The predators must think Xmas has come early. Been pretty showery/ thundery all summer here.
Get your foxing hut up there smartish. Enough bait to last all winter.
