Farm animals prefer fresh grass to hay, and become "very happy today!" (the best mood) upon eating fresh grass. They will not go out in winter, or when it is rainy, stormy, or snowy. Animals that remain inside or do not find grass to eat, eat hay instead, if it is available. | Farm animals prefer fresh grass to hay, and become "very happy today!"
