Twins are typically born in subsequent years in areas with adequate food resources. Triplets may also occur. Bucks begin antler development in spring and antler size depends on both age and nutrition. The growing bone is covered with hairy skin called velvet which nourishes the antler. The bone hardens and the velvet is rubbed off in the fall.
