We try to limit the handling until they've shed and are eating. But its funny, there were a few we hatched out this year that were really exciting combos for us (unproven projects proving genetic). They hatched while I was out of town for work, so my business partner took a ton of pictures of them right after they left the egg. We just had them out to take more pics yesterday, and they are the most laid back babies. Not even the least bit head shy. Not sure if it's a coincidence, but it is interesting.
