Sounds like she just has a major screw loose!
I'd try the fly traps too! They work out by my horse pens...but they do stink!
I'm on the fence about Roos since I had an Americana Bantam basically kill my best Bantam Cochin hen. I'm trying to give my silkie rooster a chance and so far he's very sweet with his 3 ladies, but boy is he loud even with a collar! Right now he's in time out inside the garage. Haha
I say if they're aggressive in any way, then soup pot they go even if they're too friggin gorgeous! But that's just me and that's how it is with any animal here, if they can't be nice to people or their other critter friends then they can't stay here. But like you said your guy could just be being a jerk because of the activity going on, so he might settle down.
