First I want to say I really enjoy all the stories and advice on BYC. I mostly just "lurk" here but I thought I would post my story from today. My chickens free range during the day where I board my horses. A fairly large property a couple miles away from where I live, so I am not around all the time, but guy who owns the property is there during the work day, so I didnt' have much reason to worry about my chickens. Besides that, the closest neighbor is half a mile away, so the chickens certainly don't bother anyone. I lock them in their coop at night when I go down to feed the horses, but most of them spend most of the afternoon in the coop anyway. When I showed up tonight to feed, I discovered to my dismay that someone had locked a PITBULL in my chicken coop (both latches were secured so I know it was intentional) with 9 of my 16 chickens. It was a masacre. I later found another chicken outside the coop that fell victim to the dog. So now I am down to 6 chickens. I lost both of my roosters, and I was supposed to be collecting eggs for my mom to give to her broody. I just cannot fathom why someone would do such a thing. It just makes me sick. There is only one other tenant who runs cattle on the property and he wasn't around to see any of what went on. Whoever did this was a trespasser. This act was cruel, not only to the chickens, but also the dog. Whether she was a chicken killer before or not, you lock any dog up in a 12 x 12 coop with 9 chickens and they will probably start killing. Now animal control will be putting her down (because as upset as I was, I couldn't bring myself to pull the trigger myself). Besides losing a couple of really great roosters, some laying hens, and some pullets that were getting ready to lay in a week or so, now my plans for hatching eggs have changed. This may be a question for another topic, but I figured you all might know how long my hens will be laying fertilized eggs? Looks like I might also need a crash course in incubating eggs so that I can hatch them for myself instead of sending them to my mom. What a terrible day.
