Can you keep just one horse in your backyard or does it have to another horse?

It is possible to keep just one horse in your backyard, as long as you provide it with enough space, food, water, and companionship. However, horses are social animals and do best when they have the company of at least one other horse. If you are only able to keep one horse, it is important to make sure that you spend a lot of time with it and provide it with plenty of mental and physical stimulation. You may also want to consider enrolling it in a riding or training program so that it can interact with other horses.
