I did say it was a wild notion. If she hasn't ever been broody before, she probably isn't broody now. You don't need a rooster for a hen to decide to go broody. Like laying eggs, it's strictly hormonal, but not all hens go broody.
I admit having a hen suddenly become cantankerous for no good reason is puzzling. I hope for your sake she reverts back to her old personality just as quickly.
