My vote would be for banties if for no other reason than space and handling considerations. I know when the little kids come out to our farm to pick out their chicks for their backyard flocks a lot of them are a bit intimidated by the size of a full grown Rhode Island Red or even my smaller more closely feathered EEs. When I do take these city children into a pen, I invariably choose the EE pen since those girls and even the roo there is so friendly and docile but they're still big birds. It's easy to get a claw tangled up in clothing and get hurt or get scared when the chicken makes some stupid move which chickens quite often do. To make sure no one, chicken or child, gets hurt I'd say go with a banty breed.
