I had 2 broodies this summer. I broke both of them (I didn't want to deal with hatching, etc.). First one took 5 days of me removing her from the nest box, carrying her out into the run, giving her treats, and then going back out and taking her off the box 4-5 times a day. Late in the evening after everyone was finished laying for the day, I closed up the boxes so the broodie couldn't get back in (she would even sleep in the box if I didn't close it up). I had to get up extra early during that time to go open the boxes for the others, but after 5 days of persistent removal of the broodie, I broke her. A few weeks later another one went broodie and it only took me 3 days of the same approach to break the second one.
I personally didn't want to let mine hatch because I just didn't want to deal with it. If you want the experience, count yourself lucky and let her try to hatch some. If you don't want to hatch, just keep taking her off the box, carry her outside to the run and give her a handful of scratch to distract her. Close up your nest boxes when the others have finished laying for the day and, if you have to, pick her up in the evening and put her on the roost each night. It shouldn't take long to break her.
Good luck with whatever you decide to do!
