Boer goats, and other meat goats, can be managed with only a minimum of shelter from the rain, wind and snow. A three-sided shed works well. The open side should face toward the south to take advantage of maximum sunlight and the prevailing winds in many areas. Make sure there is adequate, dry floor space for the goats to lie down during long bouts of inclement weather.
Existing barns can be "fitted" to work well with goats also. Allow an open area for the goats to gather since they are herd animals. Other types of areas may include a private place for kidding, storage for feed and hay, and a secure storage space for your supplies and special equipment.
Adequate ventilation in new or old barns should always be a consideration. Water condensation on the ceiling or walls of the barn after the goats have spent a night in the barn may indicate there is insufficient ventilation in the building. These conditions can contribute to poor respiratory health in goats.
Barns and shelters should be cleaned periodically to reduce the build up of ammonia (from urine) and to help control parasites and insect populations. The frequency of cleaning will vary based on ventilation, the type of flooring, and the degree to which surface water can and does enter your building. For new barns, place them to avoid any excess water in or near the barn. "Dense pack" gravel floors are good for use in a barn and are also inexpensive.
