Bearded dragons reach sexual maturity between the ages of 8 months and 18 months. Determining the gender of your bearded dragon before maturity isn't easy. When grown, males are larger than females, with notably bigger heads.
Ideally it is best to wait until the bearded dragons are about 18 months old before thinking about breeding, however if you keep a male and female together you don't have a lot of say in the matter!
