Farm shelters are structures used to protect animals and crops from the elements. Barns are one of the most common types of farm shelters, typically consisting of a large, open-sided structure with a roof. They are used to store hay, grain, and other supplies, as well as to house livestock. Other types of farm shelters include sheds, greenhouses, and hoop houses. All of these structures provide protection from the weather and can help farmers maximize their yields.
