That is exactly what I do. And I hydrate the night before and let it
soak all night. If it is hot, I put it in the fridge to avoid it getting
rancid. I just put in what my mare likes and we are set for the day.

Just make your own. I use big ziplock bags and put in some beet pulp, some
pelleted feed, and my horses love sunflower seeds so I throw some of them in
there too. the bags are easy to carry in a saddle pack for out of camp vet
checks. For in camp checks I take them up to the vet in area with some water
and a feed pan.
