There was no mercy however and Rose proceeded to establish her position within her new tiny herd.
and returning to post position after mission accomplished:
ABOUT FACE! Next target............
Eventually Nim managed to cross the line and Rosie took chase.
She eventually lost interest and all else was boring so, my curiosity satisfied, I pulled Rose out of the field that day. She has been doing just fine with the yearlings since Ru left last Friday even though I don't think THEY are too happy with the new arrangements. As it stands, I'm able to trust Rose out there with them full time now, even through the night.
