I figured it must be something with bantams because they go broody the most. My silkie goes broody about twice a month, but it's easy to get her broke off it. I did have the orpington broke off it for about a week and then it started broody clucking again and ended up back in the box, but I'm fixing to have eggs for her to hatch so I'm not annoyed at her any more.That will not cause a hen to go broody. Bantams are notorious for going broody - the eggs in the box / going broody is just a coincidence. That being said, please break her of being broody - she may get very sick and die, since broodies don’t take very good care of themselves while focusing on hatching eggs.
