I have plucked the feathers around the wound and treated it.... I have her in the garage with a heat lamp and she is roosting. She usually would proudly hold her tail feathers up, but since yesterday she is keeping them down and staying a little fluffed up.
She is eating fine, bright eyed and no labored breathing.... think it's just stress of the attack and injury? My husband and I were reading and looking at pictures from this forum last night and chickens that were attacked way worse seemed to have survived so I think she will be fine.... but she is my sweetest hen and I am attached to her breaks my heart.
