No other symptoms.
I separated her from the others to keep watch. Poop normal color and consistency.
She is roosting at night but I will see if she does it again. Will get up if approached. Tends to step on her own toes but they look normal.
I am kinda lost.

Legs don’t look injured and she will walk fast away. I been hand feeding her so I see she eats.
Would you not separate them?
I don’t see anything else wrong with this chicken. Less active than others and often behind or on its own
