That looks pretty good. At first, you can see Kili giving Truman a bit of "stink eye" but toward the end of the video, she has softened.
It's so funny to see her scratch her head when she wants to be petted. All three of my Senegals do that. They do it to people and they do it to each other. It is such a clear communication...."pls scratch my head". Only my Senegals do it...not the greys.
I think you are on the right track to helping them learn to read each other and also, teaching them to be flock mates.
