Quarantine is key to a healthy collection, all reptiles are very good at hiding illnesses until they are more severe and in the later stages of infection. Quarantining your new additions will ensure that any illness, mites etc will not get into your established collection.

In terms of handling, I'd handle them one at a time. Error on the side of caution and prevent any stress that could potentially be caused. When we have hatchlings and juveniles we will group them from time to time for photo shoots, but nothing more.

Yes, I wait longer. Typically we will setup our new additions and will not handle them (except for cleaning) until they have eaten several consecutive meals.
