I have hung up water buckets in the trailer, and
put a small chunk of wood in the bucket with the water. The wood helps keep the
slosh factor down as we go down the road. BUT, I decided I'd rather just do lots
of my little beet pulp mashes, extra wet, and offer them water.(then I KNOW how
much they were drinking) Without seeing them drink, I could not tell if they
were playing with the water buckets, or actually drinking as we went down the
road.
