Oh God, Parmela...I'm in tears over here. I've heard that scream just once in my life and it's a horrible, horrible sound like a giant rabbit. I've tried to block it from my mind because it's just too painful to remember that sort of agony in one we love. Especially when we can't help them!
I'm so, so sorry you lost the foal and pray that Butter heals.
