bubbles, that is awful, I am so sorry.
The dog that did this attack is from a neighbor about 1/3 mile away, and the dog still shows up on my land, and I can't get the owner to keep control of the dog. I lost 3 hens earlier this summer - every few weeks. The last one was when I came home from work, opened the run, went into the house to change and hadn't even gotten my shirt off before the dog came.
I am thinking of asking the dog owner to bring his dog over and let it get shocked a couple of times by the fence. Aversion therapy. The dog will be back. I don't have the stomach to shoot it, nor the pistol or gun.
