I really don't deserve any credit.
It was mostly a one and done kind of deal. After using the saline and cleaning around the area with rubbing alcohol, I kept 2-3 butterfly bandages stretching across the wound, pulling each side closed, like stitches. Then I put gauze and rapped her neck with athletic tape (not very tight!) to hold it all together. One of the things that I think helped the most was putting her in a storage keeper with short walls, only enough for her to stand up in without extending her neck. I didn’t want her moving very much. I’m sure it wasn’t very fun for her, but who said recovery is fun?
I kinda left her there for a good week or more before bringing her out. She went in with some young Roos and pullets who didn’t dare mess with her so no worry of getting picked on.
One thing that really surprised me was that she was still laying eggs for the first week of recover (not daily, but still), took a break for a couple days and continued laying thoughout recovery!
