I'm very late in posting this. Very late.
On September 6th, Copper graduated out of the gentling pen. It went beautifully. Jay worked with him in the pen for a bit while I worked with Skeeter, then we just opened the gate and watched to see what would happen.
It was absolutely anti-climactic. Skeeter took a few minutes to realize that Copper was really out of the pen and then they spent some time running about. All in all, it was a pretty boring release day. In fact, when my girls came to visit, Skeets and Copper acted like they'd been together forever.
