My 5 year old hen was attacked by a dog Thursday morning (July 18th). I thought she was okay after the attack as she was walking, eating, and drinking. This afternoon I examined her more closely. The photo shows puncture wounds with skin torn away. Muscle is exposed. She is now inside away from flies. I treated her with a saline wound wash solution and hydrogen peroxide. She is still eating, drinking, and pooping. She laid an egg late this afternoon. Can anyone give me further recommendations on how to care for her? What serious signs I should watch out for? Of course I am concerned about gangrenous infections...I would appreciate any help. Thank you!
