Hi, nice to meet you all. I found one of my chickens huddled up on the floor of the coop this morning, sporting drool stains on her feathers and a puncture wound on her back. My chickens free range during the day in a yard shared with two dogs. These dogs have "played with" and killed pullets before, leaving similar marks on otherwise intact corpses. I am uncertain as to the extent of the injuries. She will eat and drink, but is loath to move. My girl is able to walk, but she does so gingerly. She is clearly in pain. I'm hoping to give her an antibiotic injection, but I'm not sure I'll be able to help her if she has broken bones. Is there any way to make a cursory diagnosis and does anyone have any recommendations for possible treatment? If she needs veterinary care or equipment, I'd need to do that today as most practices are closed tomorrow. Thank you so much.
