Track system looks interesting. Where I keep my horse, they do something like this for the cows. The husband moves the electric fence every day. He closes off one section and opens the one next to it. The website I found talks about hay and water stations but there is one automatic waterer in the sacrifice area that also has the run-in shed and the chute. The cows just go back there to eat. In the winter, he will move the roundbale feeder around a bit but not as much.
We talked about doing this with the horses but haven’t yet. We do open the middle field or the circle on the driveway or send them to the front lawn.
