Yes, covered hay requires ventilation to prevent condensation and moisture buildup, which can lead to mold and spoilage. While a cover protects hay from rain and sunlight, it’s important to ensure that air can circulate underneath to avoid creating a damp environment.
Ventilation helps maintain a dry and stable environment by allowing moisture to escape and preventing excessive humidity. Proper ventilation can be achieved by leaving small gaps around the edges of the cover or using breathable materials that allow for air movement.
