I kept them for a few years, each lizard was probably handled about once or twice per year on average (only when moving them, taking photographs etc). I obtained some as hatchlings and others as adults which had been kept outdoors, I also bred heaps of them and raised a few of the ones I'd produced. The babies were tame from a few months of age (I'd call them 'tame' when they're at the stage where they'll run up to me wanting food, let me touch/hold/photograph them without any protests and have no fear of people). The adults were essentially 'wild' when I obtained them, but tamed down within around three or four months without any handling at all. They'd readily take food from your fingers or climb up your arm to catch a grasshopper on your shoulder etc, but if you're wanting a dragon to handle and/or interact with, you're best off avoiding small dragons and you really can't go past Beardies. I'm not a big fan of dragons, but I definately enjoyed the Jackies a lot more than keeping Beardies, probably largely because I'm not particularly prone to gratuitously handling reptiles so didn't appreciate that aspect of Beardies and I just find the smaller dragons a bit more interesting.
