Antler development is 3-6 months out of phase between the sexes. For example, the male's antlers begin developing in March, grow rapidly from May to July, and are completely hardend and out of velvet by mid-September. Following the rut, antlers are shed in early November by older males, but may be kept until April by some of the younger ones. Female antlers develop from June to September and are out of velvet by late September. The females' antlers are retained throughout the winter.
Pregnant females drop their antlers within days of calving.
