Yes, good point! I'll be doing that for sure. The whole thing will be sealed around the walls, floor to ceiling, to prevent anything from flying in and making a nest as well. The exterior wall of the barn adjacent to the interior wall of the tack room will be sealed too.
Home tonight and I'll be turning my attention back to the fence installing the rails. It's going to start having that "ranch" feel! Hot wire on the inside to keep horsies in....hot wire on the outside to keep neighbors out!
Cheers
