I recently purchased two bearded dragons. One is a juvenile while the other is not much older than a baby. The baby bearded dragon is very accepting of holding and interaction and doesn't do much besides bask. The juvenile seems absolutely terrified of human interaction and even puts itself in danger (trying to jump from pretty high, I am 6'2", to the ground). I am concerned the dragon might have been mistreated to be absolutely terrified as it is the first I have owned that is scared.

The two dragons are in the cage together and get along fairly well. There is no fighting or dominance issues.

Is there a way I can break his fear? Should I consult the sellers about possible mistreatment?
