What? You disagree with me? Your in trouble now boy!
Just kidding LOL
Two weeks is a long time to be completely 'hands off' with a new pet and it definitely doesn't mean handling before that time means your dragon will be stressed etc. I give 2 weeks mostly because it ensures they are well established and eating well, used to their new home and familiar with their knew owners.
Some dragons adapt alot faster than others, so 2 weeks of hands off is not a hard rule. I also know most people with a new pet won't have the patience to wait two weeks....but may wait a couple days at least or maybe a week. A week is a good time to wait, better than one day or no days.
It does really depend how the dragon accepts his new home. Some dragons will treat a 24 hour or longer stint in a box as a nice long rest and as soon as they warm up in their new cage, are ready to chow down and act like nothing changed. They may also take to being handled much faster. So playing by ear is good to. If a few minutes of daily handling causes no change in eating/behavior patterns (in a negative way that is) then a couple days may be perfectly fine. Alot of newbies dragon owners mistake the 'freeze so they can't see me' reaction of terrified dragon as 'he is so calm, he must love being handled'. More often then not, the dragon will realize freezing doesn't keep the big huge monster from hovering around him, and decide fleeing is the next best thing... then the new owner wonders why little dragon was so calm for the first couple weeks and now is psycho dragon.
Hence why I suggest two weeks.
