Last Wed. 8/18 late afternoon, heard a commotion in the yard. I looked out to see a young rooster doing his clumsy best to mate with an older hen. The noise drew the attention of small dog, which until now had never shown any aggression towards the chickens. Dog apparently felt he needed to get in on the action and attacked the hen. Her injuries are to her back and around tail feathers and upper portion of wing where it joins to the body. I washed her up with Betadine immediately and applied Neosporin and tried to wrap with gauze and vet wrap, but it wouldn't stay on. Got to the farm store early Thursday and purchased Vetericyn. I was told to only use one form of treatment and to not mix it with anything else. I have been spraying Vetericyn on the wounds 4 times a day. Gave her antibiotics and vitamins in water as well; yogurt and some acidophilus. Mixed up a variety of food, starter, layer, scratch, grit and she is eating well. She loves the fresh watermelon and vegetables. She even laid an egg on Friday! 2 days after the attack, this totally shocked me. My problem is that although the back injuries appear to be healing OK, the wing injury has a putrid stench. The bone was exposed and tendons torn and ripped. I'm pretty sure her wing is useless as she can't move it at all. What are my next steps? The injury is in on the inside of her wing next to her body and it's very difficult to reach. It's not drying out like the back and tail area. She is in isolation with heat lamp. I had to leave town right after this happened for work and my pet sitter did an excellent job of caring for her, but now that I'm back I feel like I need to do more. Do I change the course of treatment? I'm concerned that washing her down again would make the area wetter and worse. Should I be cleaning the wound daily with Betadine, drying as best I can then spraying her down with the Vetericyn. Thanks for your advice and input. I hate that the worst predators I have are my own 3 dogs.
