Last week, my chicken was attacked my an opossum and he attacked her rear (inflicting 2 holes on either side of her butt). We poured hydrogen peroxide on the wounds and today, I applied neosporin to the wound. She has been pecking at it every so often (I really don't know how to properly cover it) and has been lying around a lot, seeming to be weak in her legs. She also rests her head every so often. She has not had an egg since the day after the attack. There is also a strange smell to her. I'm not sure how to further address these wounds, or even if its better to put her out of her misery if there is not a chance she will live. Any advice is greatly appreciated, because I cannot stand to see her suffer any longer. Thank you.
