If she just started acting broody, you'll be able to break her more easily than if you let her stay that way for awhile. I found that out the hard way with my Buff. I figured she'd snap out of it if I booted her off the nest a few times a day and took all the eggs away from her. Nope, she'd sit on the empty nest with a crazy look in her eye. I even dumped her in the duck pool and she stood there in water up to her chest and just stared around vacantly and didn't try to get out. Once it went on a few weeks, she was so determined to stay that way. Now, when she goes broody, I right away put her in an empty dog kennel for a day (empty as in, no bedding- she has food and water) and she's back to her normal self by the next day.
