Fox attacked by Chicken - do I crate her, or put her out?

[Tesumph]

We are using this spray and the Blue Kote, she seems to be healing. We will let her out with her sisters for a little bit - UNTIL this morning. Even her sister is pecking at her. What does that mean? Pain must be setting in, she definitely does not like it when it's "clean and smell" time.

Unfortunately cannibalism and preying on the weak is just part of owning chickens. A hen saddle would really help in this situation, since the wounds are on her back.
Glad to hear she’s healing!
