My DD forgot and let the ducks out. When she went to feed and put them away, she found that our dog had one down. He plucked the feathers off the back of her neck down low but mostly on her back close to her neck. The skin is broken a little bit in a large area (like like hamburger thought like the last one since we caught it in time). I put neosporin all over the area after we ran water over it. I really wasn't sure what to do. She is not eating but she is drinking. I sure hope she recovers. The dog has been with the chickens since Jan/Feb with no problems. The ducks have free-ranged since about Aug. I'm thinking he was bored and figured she was a nice little toy. He has some stuffed animals that he's pulled apart. So our ducks no longer free-range from dusk to dark. This last episode is imprinted on all the minds around here.
