Seriously Broody Hen Fix?

[littlepeepers]

Two of my hens, a Black Australorp and a Buff Orpington have been broody for about 10 days. We you get close to them they puff up their feathers and make their little defensive noise. I noticed today when I went to take them out of their coop to get some fresh greens that both of the chickens had plucked off the vast majority of their feathers on their belly. We don't have a rooster, fertilized eggs, or a want for more chickens. Are there any recommendations for trying to get them to stop this behavior?

I found a page full of threads on the subject with a quick search. Use the search function at the top of the index page, keywords "breaking broody" in the sub-forum 'chicken behaviors and egglaying' and topic subject only.
