My Welsummer pullet was attacked and partially eaten by an owl on 10/16. I've helped many chickens who were attacked by dogs, foxes, and coyotes, and know they are amazing at healing. This one I wasn't so sure about, but thought she deserved the attempt to save her. When I found her, the owl had eaten the skin and all the muscle on her back around and between her scapula (shoulder bone) and backbone. The wound between those bones was about 1 inch deep. In the second picture, the Left arrow points to the top of her scapula, and the Right arrow points to her spinous processes. There were bubbles coming out of the puddle of blood between the two, and I could actually hear her breathing through the wound. It must have been a ruptured air sac. The photos are in order, the last one taken tonight. This photo is day 3. Note the green color to the tissue. This is NOT gangrene or rotten tissue, but the normal color of healing tissue in chickens. (Their hemoglobin breaks down into green pigment, not yellow like ours.) This is two weeks (Nov. 1.) Note the healthy pink tissue, and the contracture of the wound edges. You can still see the tip of the scapula and spine (arrows.) Today... All healed! I will keep her away from any roosters for a while yet while the scar tissue thickens!
