Sheep are animals in Harvest Moon: Animal Parade.
All sheep need to eat fodder daily, but an adult can be let out to graze on grass instead. A healthy sheep can be both sheared and milked once every 4 days, even if it's outside. The quality of the sheep milk and wool will depend on the animal's affection with you and its health.
To raise it's affection a sheep may be brushed and pet daily. It takes 7 days for a pregnant sheep to give birth and another 15 days for a lamb to mature into an adult.
A healthy sheep may produce both Wool and Milk every 4 days and the quality depends on the sheeps affection towards you and its overall health.
