My little EE was attacked by my BR chickens, they tore the skin and muscle off of her head so that her bare skull was showing! They also pulled all the skin off her neck, that was two weeks ago- I cleaned it, separated her, and put neosporin on it daily- she is getting better every day- the skin on her neck is growing back, and the muscle is growing back over her skull. Chickens have a remarkable ability to recover so I am sure your girl will be okay! You are doing all the right things.
