when do deer give birth
The gestation period is about 190â200 days, with fawns born in the spring, staying with their mothers during the summer and being weaned in the fall after about 60â75 days. Mule deer females usually give birth to two fawns, although if it is their first time having a fawn, they often have just one. A buck's antlers fall off during the winter, to grow again in preparation for the next season's rut. The annual cycle of antler growth is regulated by changes in the length of the day.
