Tired Wilbs. He's made best friends with Sunshine in the next paddock over and was quite relaxed in his lesson today. We cut out his grain which I think will make a huge difference in his behavior. Grain provides sugars and carbs (and nutrients) to help with performance. Since Wilbur isn't working that hard I think that extra boost in energy was directed, not towards work, but towards his scaries.
Time will tell. Kelly made an excellent point- change one thing at a time so that when he does settle we know what works for him.
