Here is a pic of her with her new bit.
As you can see, she cannot close her beak and therefore cannot pull feathers. I also trimmed her upper beak back to the quick and I know I'll have to keep trimming it, probably weekly as it will be growing quickly. I hope she stops this ugliness as she really is a pretty little thing and I'd like to keep her. However, in a few weeks when I take it off, if she resumes her attempts , I will have no choice.
She is getting plenty of attention but no one is being mean to her but her attitude is definitely a lot different than it was earlier. She may still get lower on the pecking order... that's ok. As long as nobody pulls feathers.
Fingers crossed

My girl still has her peepers on and they are still working, knock on wood.
Feathers are growing back! Cindy, who was the worst picked on is starting to look good again. The feathers are starting to emerge from the pins so now it looks like she's got little paint brushes all over, if that makes any sense, lol.
I figured out that only two of the four are molting. I hope the other two don't wait too much longer so its not super cold when they do.
