I’m so glad your chicken is holding her own-when the chickens on the ranch were ganging up on a weak or ill one, someone was assigned the chore of taking that hen out of the main yard and putting her in a small pen with a box-built for just that-where she could be given meds and eat in peace for a few days-it worked fairly often...
My other 3 year old hen, Penelope, who was raised with Dixie, has been sitting next to her on the ground, just keeping company. It’s sad and sweet at the same time. It’s as if she knows her old friend isn’t well and is protecting her and providing comfort.
