Beak trimming is the least of the worries for this bird...Does anyone else think the chicken needs its beak trimmed? I see a parrot beak situation there.
If she doesn't get nutrients... she is dying!

WHAT GRAIN ARE YOU FEEDING????
You have some of the best people here trying to help you... but if you won't listen or can't hear the truth then we are wasting our time trying to help. Dork, I get! You're in good company.

Maybe a little blatant... but NO rudeness intended.

For ME... as a last ditch effort... I will offer raw egg yolk from my own flock... recognizing there are possible issues that could be caused by that like salmonella or whatever.. never had it happen yet. I know nutrition seems like too simple an answer if you haven't experience previous issue... but it's never a problem until it is. She is a dual purpose breed and maybe just isn't as good at foraging or is better at hogging the low nutrient grain than some of her flock mates that are doing better...
Were you able to get a poop pic?
The head leaning to the side does make me wonder.. I don't usually see that in a resting chicken. It is usually pulled in or tucked one direction or the other. How does it look when she is actually awake?
I personally cull illness out of my flock. But if I was gonna let her stay I would let her stay with the flock as long as she wasn't being picked on. I agree chickens get lonely and need some support from friends. MAYBE that is the reason she escaped.
Come on Warf... show us that fighting Cling-on spirit, so we can explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before!
