I am a new chicken owner, I had my flock out free ranging this morning. I had just checked in on them, walked inside for 2 mins, loud commotion outside, I headed out back and my chickens were scattered all over our yard. I found one of my chickens in the front yard, she was injured. The skin under her feathers is torn, it seems to have stopped bleeding, but I need to know if I can nurse her back to health or if trying to heal the wound is just causing her to suffer more. I have separated her from the rest of the flock, but again since I am so new to chickens I am not sure what to do about this attack. I have a sneaking suspicion it was a hawk since one is still circling our yard. Any information would be much appreciated! Please help!!
