First I want to say that I think it's great that you've been so patient with them!!! Not many people would do that!
If you've had them since Wednesday, then I think it would be okay to start getting them used to your hands...being pet, scratched, etc...
My Santino had NO problems being touched. Right from the get go! Barney, however, is a bit skittish, so I'm working with him on that.
I suppose you could approach them and see how they react to your hand, and go from there. But I don't see anything wrong with handling them now.
