Mid-day yesterday my Australorp chicken was attacked and now is missing all her back feather (see pic) some tail, and some underneath. She has some small wounds. She is walking, eating/drinking, laying down resting. I washed her down with peroxide/water mix and let it air dry. Added Pedialyte (for electrolytes) to her food and she ate some of that. Is there anything else I should be doing?? She is separated from the other chickens and has a nice little box/house that she slept in last night. Today she's seems the same as yesterday. Should I wash her a few times a day with peroxide/water? Is there some antibiotic spray I should get? Thanks for the help!
