Hello! I am brand new to this site, and brand new to lambing! One of our ewes had twins 5 days ago. They were in a jug, but the last two days we have been letting them back in the paddock for a few hours with the other two ewes. One of the ewes (who has always been on the ornery side) was fine yesterday, but headbutted the little ones today, pretty harshly. Gertie (the mother) tried to stop some of this, but couldn't stop all of it. Should I be concerned? Is this normal behavior? It seems the little ones could get hurt, she butts hard. I would separate her, but then she would be alone, and I know that sheep are not supposed to be alone. Any advice is so appreciated!
