How can you get a hen to go broody?

As you might know we don't have very many hens that get the opportunity to go broody but lately I have been thinking about breeding a few of our prize couples from good stock because several people have asked us if we would be interested in selling them some from these pairs, such as our black Buff Orpingtons, Seramas, and Phonix of which we were blessed enough to acquire. I would like to make the process as natural and comfortable, as possible for the mating pairs. I would like to hear from ya'll about the best ways that you have found to encourage your hen to go broody (sit on eggs until they hatch) and what to do after she does and as always I am looking forward to hearing from you.
