Here's why:
* Natural Behavior: Horses are grazers, meaning they eat grass and other plants. They need to move around to find fresh pastures.
* Social Structure: Horses are herd animals and live in groups. They move together to find food and water, and for safety.
* Escape from Predators: In the wild, horses need to be able to run away from predators, so they are always on the move.
However, horses can be domesticated and kept in one place with proper care and management. This includes providing them with:
* Plenty of space: A large pasture or paddock with enough room to roam and graze.
* Adequate food and water: A consistent supply of fresh water and nutritious food.
* Social interaction: Companionship from other horses.
* Shelter: A stable or other protection from the elements.
While domesticated horses can be kept in a specific area, they still need opportunities to move around and engage in natural behaviors to remain healthy and happy.
