Chicken Neck (Yucky picture to follow)

I finally got a picture of the lady who has the feather’s missing from her neck. I wanted to post them to see if anyone had any additional advice. We are keeping the purple spray and a lotion on her daily. I may have to isolate her though if it doesn’t get better soon, but I hate to as she loves being outside and jumping the fence to explore. So if you have any ideas on what it could be or if you have dealt with this before let me know your ideas. Thanks 🙂 chickn neck
