Poor you!
Poor Dragon!
I'm glad everything calmed down though!
Criminy!
I use pedi paw on my cross beak pullets beak. 
She lays very still and lets me do what I have to do. I do a little on top and a little on the bottom because it heats up and I don't want to burn her.
Just go back and forth between the two.
I picked mine up at Meijer, but I've seen them cheap at 
walmart too.
They come with an extra head too, refills aren't too expensive either.
I have to trim my Penelope's beak, if I don't she can't eat.
I don't know if Dragon's beak is that severe.
Penelope was freaked out the first time I did it, but she noticed "Hey, I can eat better!"
So now she just stays still and waits until it's done.
