Through the hedge: image resolved.

Near us, the fields are full of fat, pregnant ewes.

However, today I went to the town the far side of the nearby hills and drove past a field of sheep there.

Through the hedge, I thought I could see a load of sacks in the field. They were scattered about, all over the field. White sacks, tied at the top to create two little handles. Small white sacks, tied at the top, with ewes very close to them.

And then the image resolved, and the field was full of ewes, and little baby lambs sitting next to their mothers.
