Our chicken, Amelia got into the neighbor's yard and their dog got to her. She has several cuts on her back and shoulder. We loaded them up with hydrogen peroxide and some petroleum jelly. We saw her meat.We put her in a large dog kennel with bedding, food, and water with vitamins and electrolytes. She's in our garage currently. Since it's chilly and she has exposed areas, we put a small heater in front of the kennel. Any suggestions on what we can do?
