We left our ewes empty last year, they were rather fat going to the tups, but nearly all caught. It also meant they had extra reserves going into winter, it worked out well for us. Not the done thing I know....
If she would here we d put her on rather scant grazing, on a hill maybe, we d be worried that she would get stuck on her back. Saying that we lost one ewe one night last week, kept one part of the flock on a hill and she only went and got cast across the hill in a little dink.... Sods law...gutting x
