Last night a predator was able to gain access to our coop. We lost one hen, and another is badly injured. We are trying to give her the appropriate care, and are searching this thread for recommendations. Her injury is severe, to her back. Skin layer is missing, and has exposed muscle underneath. She is walking, eating and drinking. We have her separated so she remains safe from the rest of the flock, and calm as we determine how to help her. We have applied Wonderdust, and Bluekote so far. We would like to give her a pain med. Aspirin has been discussed as on option on the threads. Our concern is that the wound is too severe to heal. When and how can we make that determination? Also the infection factor due to the severity of the wound. Any thoughts, direction or recommendations would be very appreciated. Thank you.
