I'm with everyone else - I think keeping them close makes them much more used to the comings and goings of people in general. Mine have just moved out of the house and are very accepting of me walking among them, moving stuff around, whatever I need to do in their house or in their space. They don't love to be held but they definitely like to follow me around and obviously feel safer with me around. Just keep in mind that they make a lot of dust as they grow their feathers - your house will have a white dusty film over everything by the time they're ready to move outside. Not a big deal, but be ready to do a deep cleaning when they finally "fly the coop".
Enjoy your chickies!!
