As with any antlered animal there is alot of variables. The type of forage they have for antler growth and the availbe minerals they have in there habitat also you have to take into cosideration the genetics of the bulls from a given area.
Most of the time they have there first set of antlers by age 1 1/2 years old and usally they are only a spike but this is where nutrition and more so the genetics play a roll on antler size and configuration. I have seen 1 1/2 year old bulls with 3 and sometimes 4 to a side but not real common usally they dont branch until they are 2 1/2 years old then they can be anywhere from 3x3 to a 6x6 again genetics is key but this does not mean they will have alot of mass to there antlers.
