The classic way to break a broody is in a wire cage with no nesting material, propped up so there is air flow below her, with food and water, of course. Even with a fan blowing on her underside. The cool air apparently breaks the cycle.
I have broken the "sort of" broody ones just by taking them off the nest and chasing them outside several times a day. I have had the wire nest method fail; had to buy her some chicks to raise, to stop her.
Lots of people just let a broody set. Sometimes I do, too, but I kick them out every time I am in the coop. If she does it right, she will get up and eat, drink and poop at least once a day. Occasionally you will have to make a broody do this -- if you find poop in her nest, you need to ensure she gets out at times. Broodies do lose weight; in some cases, too much weight. Occasionally one who is not sitting on fertile eggs will actually die. As with most things chicken, it varies with the individual.
