More shedding

I tried Sprite next on shedding the large group out away from a fence (ok, it's not that large, but it's the bigger than the small group).   She did it just right the first time which I was not expecting.  I made a hole for her, called her in, she came in and turned on to the sheep I was facing and drove them away.  I thought it might be fluke so I tried it again and no, it wasn't a fluke.   I guess she knows it.   I could make it harder with stickier or smaller groups, or not making the hole for her, but I think I'll stick with our success for now.
