We always gave the overeating shot and I can't remember what others as it was 10 years ago that I had sheep. I still miss them to this day. I loved raising them so much and my ram was just a big sweet puppy dog. I had a few ewes that followed me around everywhere. I know one day my ewes kept me alive when I passed out in the barn on a -20 degree day and awoke to find my ewes all around me keeping me warm.
