Another update. Smokey has been turned out with some other horses (4) just as he wanted. He galloped out to see them (approximately 30 acres in this pasture), looked around and then came right back! The mares came to water and went numerous times and Smokey stayed. Can it be he has never been in a large pasture? Poor thing was certainly insecure about the whole thing. Want's to stay near the barn (like a horse running back into a burning barn, I guess). Anyway it has been several days now and, while I would bring him in for feeding to make sure he got his fair share, out he would go afterwards. He has finally learned that there are wonderful things out there to eat and look at. Round ring/riding wise nothing has been done till I finish classes but he is adjusting quite well.
