How do I make this stop?

Helen, my 3yo Australorp, is broody. This is my first broody hen ever. Normally docile Helen is sitting on the eggs, growling and turning her feathers inside out and just being a pain.

How do I encourage her to return to her 'unbroodyness'?

Take her eggs. Try putting her in a cage with a wire bottom the wind on her belly should break her.
I know all about broodies... stupid silkies are always on a nest...

We are taking her eggs daily. She's not only sitting on her own but on the two other hens' eggs as well. It's a fight to get the eggs; we are using a baseball glove as a shield.

I don't have access to a wire cage. One thing we have tried is locking her out of the roost box but then the other hens are locked out as well.
