It goes without saying that you'll need to purchase "Sweet treats" for your sheep, which you can do with the MARD tokens that you earn. Alternatively, automatic feeding can be enabled to save both time and effort on your part. When the level of hunger in sheep falls below 50%, this mechanism kicks in to provide sweets for them. The amount of wool produced by a sheep decreases dramatically when its hunger level falls below 50%. If it reaches 0%, the sheep will no longer be able to generate any wool at all until it has been fed again.
