This hurts my heart. I'm so sorry for you and your family having to go through this. It hurts for such a long time. But you are not alone believe me. 20 yrs. ago we had 12 wonderful girls. Doting and attentive. Wonderful girls! Then a police officer (no not even a nice cop!) and the family moved into the house by the road. About 1 acre away from my land. With them came a family "Drug sniffing police dog" {?? not!} After multiple efforts to ask, pled, threaten, beg him to control his dog and not let him run wild on my land, I was informed: "he can go where ever he wants He is a cop dog".....I am not a mean or evil person. How can you love a chicken and be mean? (Easy, I could have shot that dog and the human laughing at me, easy) So we wretched up our attention to the girls. From goat fencing to chain link. (I hated it. From my deck it looked like a prison yard.) All to no avail. Coming up the drive to the house (1/4 mi.) my eyes glued to the coop and run. Dead chickens and chicken parts and feathers all over the run and that awful dog riping up the remains of one IN THE RUN. We pull up, I'm screaming and that Good cop dog climbs up and over a 6 ft. chain link and runs back home to daddy. I'm distraught, husband calls the local police and there is nothing they can do. No rules about dogs killing chickens. "Anyway, he's a cop dog he can go and do whatever he wants, can't help you" That was it, I was done with chickens and humans and cops. You know, it's not the dogs' fault, it's the humans'! Dogs are what they are taught. Like kids, you are given a choice of how you teach. Good human or gang member. We got back into chickens again and we have 3 dogs. Everything is fine and all was taught well. We doing it again! Oh by the way. The cop family moved. He's in jail for domestic abuse. I'm glad there is a rule about that! Ps. One of our rescued dogs (10 wks old) is a Pit name Sam. Anything in the back I don't want like a dog, Sam pulls a bead and off the deck he flys. I call him off before he catches (he is remarkably smart and loves me. But he is a pit, he doesn't have free run of anywhere, I know) and we haven't had an issue in 4 yrs. What an awful experience for your family, My deepest sympathies.
