So i was walking out to the coop to give my chickens some yogurt and blueberrys when i hear one of my chickens squawking. It was not a usually noise, so i knew something was wrong. I went around to the barn and saw our renters heeler puppy running out of the barn..so i started walking down the isle and saw my roo attacking my golden and she was just standing there like what did i do. He stopped as soon as he saw i was there to take control. So i just thought it was cause she was there and they got startled or something. So i set the bowl down for them but they didn't want any of it which now that i think should have been the first clue something was wrong since they all come running for yogurt. A few minutes later my sister who came out with me notice my Lavender ameraucana under a shovel. I ran over to her and found that the heeler had attacked her. He cut her open on the back and riped up her wing so bad the bone is showing. . I was so mad i throw my flip flops at the dog and then tended to her wounds. I have her separated from everyone in a large dog kennel with a towel down so that the wounds stay clean. I also medicated the water and gave her some food and blue coated the wounds. When they get him im telling them if there dog kills any of my chickens or attacks another one there dog will be gone. This sucks so bad cause it always happens to my favorite chickens.
