"I'm just looking...."

If you believe that, you'll believe anything!  Last night as we were going to bed, there were four of these young lambs the wrong side of the fence and of course they were crying for their mothers who were just on the other side of the fence trying to encourage them to get back in!  As Mr Sk says, they got out so they can get back in the same way!  The bleating finally stopped as we drifted off to sleep so I guess that's what happened.
