I’m trying to come up with an inexpensive way to keep water troughs from freezing without using electricity.
The solar powered waterers are out of the question due to cost. I have found reasources on how to make your own insulated water troughs. These look like a great idea but I am wondering if there could be a simpler way for climates that usually hit the 30s temps during the day. The horses are out during the day and in at night in the winter.
From my reading, it seems that ice is less likely to form if the water is moving.
First I found these that duck hunters use to make their decoys look more realistic. They are inexpensive but the batteries only seem to last 4-6 hours so that would get expensive on a daily basis.

I have heard that semi deflated basketballs or footballs work by their movement in the trough helping slow down the formation of ice. I have also read that covering most of the trough so that only a small surface of water is open to the air will also help keep the water warmer.
My first thought was to make a type of “floating dock” on the top of the trough with a hole cut out for water access. As the water level dropped, the “dock” would go with it so the horses wouldn’t be putting their heads down into a deep hole in order to get to the water. I thought I could make it out of plywood mounted on some sort of Styrofoam or even old life preservers or such. I think the problem is that most troughs are wider at the top so the floating dock would probably still get stuck somewhere on the trough sides. Is this a feasible idea?
My next thought was people who do ice fishing must have a way to prevent the holes from freezing over. They do make ice fishing covers like this one
They are black so they would absorb heat from the sun, they would float and if I attached them to something heavier, maybe they would bounce in the water enough to help slow ice formation. If I used the covers at night on the hole in the ice that they drink from, would this work?
It is usually not for days on end that we have frozen troughs so I just wanted something for the freeze spells.
My other thought was to put a few jolly balls or buoys in each trough to see how that works.
Am I crazy? Has anyone done this? Does it work?
