How to grass feed a horse
Choose and prepare your pastures.
Before getting started on grazing your horses, you need to do a couple things to prepare, like choosing pastures and fencing your pastures. Multiple fenced pastures are often necessary because of the lifecycle of the grasses in your pastures and the demands your horses will put on the pasture ecosystem.
Consider : Having at least two (or many more) pastures, a spring/summer pasture and a fall/winter pasture. Making sure your pastures have proper drainage and don't have large holes or other dangers that could harm your horses.
