A quick search will turn up many others.
As for a hen setting eggs and raising chicks, broodiness has been bred out of many chickens, or almost so. Henderson's says your breed "can be broody," so you would probably be lucky to get a broody out of 5 hens. If they are over a year and none have gone broody, they probably won't.
There are breeds that always or almost always go broody. You could get one hen and let her set the eggs from your Hollands; they won't care whose eggs they set or whose chicks they raise. I agree, I want my chickens hatching their own eggs and raising their own chicks.
