I suggest you try pinless peepers. The device is very inexpensive, harmless to the bird, cuts down on forward vision, and could at least slow down her predations, if not curtail them altogether.
I have a seven-year old GLW and boy was she ever a terror in her youth! She's still the only one in the flock who hates me, though she's long ago given up her bullying ways.
