Sorry if this question has already been talked over, but the search tool was no help in this case.
My horse and I are attending a horse fair in 3 weeks time. We will go there on Friday evening and leave on Sunday afternoon. He will be provided a fenced paddock with grass for grazing, and I will bring my hay - just in case. But the question is about his hard feed. Normally he gets about 2 lbs of oats a day and an additional ~2 lbs of a pre-mixed feed 5 times a week. But does feeding have to be any different in show and trailering circumstances - should he be fed just forage, or should I take his usual portions of hard feed with me, too?
