I read somewhere that the broodiness has been pretty much bred out of the modern day chickens.
It sounds like you are hoping to find good mother hens.
Most, but not all breeds have indeed been selected over time to exclude broody traits. Bantams of any breed are generally good mothers and good setters. Most cochins are also this way.
If you have hens that are broody and you don't want them to be broody the single best thing I know of is to move her to another chicken coop. If she still wants to set, which is unlikely, move her again. She will start to lay again and act more "normal".
Since we raise our own chicks from our own eggs we really appreciate a good broody hen as she takes the eggs all the way through incubation (better than a commercial incubator) and teaches them how to eat and keeps them warm without artificial heat, etc.
To us it's a grand thing to watch. And we don't have to tend to the chicks nearly as much.
I do understand that most people just want to buy chicks, have them lay eggs and not deal with the rest.
I do not know how to get a chicken to be broody if she is not inclined that way. We have had some that were broody, would set on eggs and then be terrible mothers also.
My best advise if you want a good mother/setter would be to buy hens from a breed that is known for being good moms/ setters.
