They probably didn't get too much - they didn't pig out on it like they do the sheep mineral, and there is always plain salt available. I pulled it as soon as I found out about the copper.Horse mineral has a high copper content, too much for sheep. It takes time for it to accumulate in their liver , so your sheep might not have got too much. A little is good, too much and one day they die and you don’t know why.
