My 10 month old hen was attacked by a dog three days ago. She's eating and drinking including antibiotics in her water, but she's missing a large patch of skin on her back. I have irrigated the wound thoroughly and have it dressed with surgical gauze made for open wounds as such. My concern of course is infection and whether she will recover such a large patch. It's approximately 4 inches by three, or from wing to wing and bottom of her cape to middle of her back. We sure do love our chicks and having lost one in same attack, would hate to lose our trooper now. Any advice or help is appreciated. Thanks folks.
