Julie,
You explain everything so well

.
bcnewe2,
Yes, Julie suggested real life tasks, and I explained that I really want to and I will try but that there are difficulties in designing a doable task in an open area for a young dog.

When Kelly was growing up we had a mean ram to boot. So Kelly has grown to be a very strong and
extremely fast dog. I didn't know how fast she was until we had the instructor come to us and I could compare my dog against his dogs. I will never forget when he came, placed his dogs in the enclosed area, where the sheep where, the little rascals just stood there and looked innocent. He turned to us and said, "this is how sheep behave when an experienced dog handles them." That was their cue - the sheep found a weak spot in the positioning of the dogs and shot out of the the enclosure and off into the sunset

. They also presented later what I call a "Cameroonian maneuver"

. I am sure other sheep do it too, it's when a sheep goes directly at the dog, the dog summons all of his eye-power to stop the sheep, and the sheep instead of backing off, speeds up and jumps a clear long jump
over the dog.
Now for mixing Cameroonians with other sheep. We did that of course. First we had two flocks. The dynamics and reactions were so different we had two different flocks, and working with them was one big mess. Then the Cameroonians calmed down a little, and the woollies got a little turbo charged. Then the woollies started to teach the hair sheep bad habits of going thought he electric fence, and we had to fix it sometimes every day. And then we sold the woollies, as they had had no further influence on the other sheep. However, the ram went to live with a large flock of woollies and he behaves just like them. He produced a bunch of crosses with the hopes that the woollies will be a bit less sticky. We will see if it worked.
We live in a non-sheep area and are able to sell the lambs because the are pedigreed. The mixes we just about had to give away. the wool is impossible to sell. People with wool sheep jut burn it.
