Feeding a horse on the ground has its benefits. It minimizes the risk of choking. The chances of colic and respiratory diseases are minimal when the horse bends down for every bite. Some people believe that a horse should be able to reach the hay in its natural neck position. So, the haystack shouldn’t be any lower or higher than 4-5 feet above the ground. However, in the end, how you choose to feed your horse is your and your horse’s personal preference.
