We came home this afternoon to find all our chickens huddled in the front corner of the yard, so we knew we had a problem. I went looking in the back yard and found one of my hens, alive, with multiple wounds on her back and sides. She has some straight wounds that look like cuts and others that are superficial areas that have no skin or feathers, about the size of a quarter. She has a sideways straight cut above her tail. I brought her in the house and she is eating fine. I think she will be okay, but am at a loss as to what might have done this. Any ideas? As a note, we do have two dogs that have NEVER harmed the chickens before. I took these pictures today, Monday, the day after it happened. The first and third pictures are of the same spot on about the center of her back. The second picture is on her side. I did not want to stress her too much, so these are the only pictures I got.
