Corrals are turnout areas designed to confine horses while providing them with an opportunity for moderate exercise. They are generally square or round, and are often attached to barns for convenience.
A corral should be more than an effective containment area; it should also be a safe, open place in which to romp. A durable perimeter fence 5 to 6 feet high is the standard, with no sharp edges or protruding nails.
Be aware that clutter on the ground, or rough surfaces, may invite injury. Size is also a factor; the possibility of injury increases as the size of the enclosure decreases. A typical corral is 1,600 square feet.
