So as we continued to work at getting Bucky going under saddle, we can't help but notice - this horse has an amazing play-drive. He plays with *everything*! He has the usual likit's and jolly balls that he plays with on a daily basis, along with anything else moveable in his paddock. It is not unusual to have to hunt for his feed pan (in Lady's paddock) and his jolly ball (in the hay field) on any give day. He will also play with tarps, kiddie pools, blankets, grain bags - anything left in his paddock.
We also bought him a large "yoga" ball to herd / play with. I was hopeful this would give us a good foundation for cattle work someday. He certainly liked it, he also destroys them frequently so can't be left unsupervised with a large ball. You can see video of him playing with his ball at these links (its pretty amazing): bucky playing ball one and two.
