Whitetail Deer Birth and Fawn Age

Whitetail deer females give birth to 1–3 spotted young, known as fawns, in mid to late spring, generally in May or June. 
Fawns lose their spots during the first summer and will weigh from 44 to 77 pounds (20 to 35 kg) by the first winter. 
Male fawns tend to be slightly larger and heavier than females. 
For the first four weeks, fawns mostly lie still and hide in vegetation while their mothers forage. 
Fawns are able to follow their mothers on foraging trips. 
They are weaned after 8–10 weeks. 
Males will leave their mothers after a year and females leave after two.
