I think you can handle them after they're 10 days old,so you can safely pick them up. Just make sure your hands of course,are clean,and just gently move them mother to a another cage temporarily,and you can gently pick up the babies. When your done,rub your fingers on the shavings to mask your scent,and then set the nest back,and you can bring mom back to the cage. Pretty sure that's how you do it,I read it on a website.
