Hay covers are generally not needed in barns if the structure provides adequate protection from moisture and pests. A well-constructed barn with walls, proper ventilation, and a dry, elevated storage area can effectively shield hay from environmental factors like rain and snow.
However, if the barn is not fully enclosed or if there are issues with humidity and airflow, supplemental covers can help protect the hay from potential moisture and mold problems. In such cases, breathable covers or tarps can provide an extra layer of protection to ensure the hay remains in good condition.
