I had sheep once they drove me crazy any time you would walk across the yard they were blating and carrying on. I live 3 miles from the sales barn and one wendsday (SALE DAY)  They went to blating so I hooked up the trailer and grabed some feed and layed a line of feed down the floor of my 28' trailer shut the gate problem solved. Now the youngest here is trying very hard to buy some ewes.
