I actually had one of my 'Zons go berserk when his claw got caught in a toy in his cage. Remember, their toes are incredibly sensitive, and a caught nail could be extremely painful - the more the bird pulls, the more painful it becomes and, with long nails, the tighter it embeds in whatever it's caught in. He pulled & pulled, screaming as loud as he could. I was finally able to towel him & used pliers to tear apart the toy and free him, but he was tearing chunks out of that towel, plus everything else in reach.
One freed and given a few minutes to calm down, he was contrite & very loveable.
This seems more likely to me than a hormonal spike. I've seen lots of those, too, but you can generally see them coming - the bird starts getting fussy, and over a few minutes, builds up a head of steam.
If this is, indeed, what happened, it's easy to ensure that it never happens again, and she can stay in her home & enjoy life!
