Ooh, very sorry for the both of you. 
Maybe now its the time to help her out of this misery. ? You know best when the time is right.
I read about using an airtight box and starter fluid (ether). Overdosing ether seems a painless dead. It is something I intent to do if I have a very sick hen in pain that needs an exceptional miracle to heal. It’s not something I would do easily. I rather give the chicken some time to heal and show progress. Just like you.
Good luck
