I'm about ready to loose my mind. My stupid mutts that I just got has killed half my flock! Now it would appear they found away into the coop and no chickens just feathers! I've tried beating the dogs with the dead birds. I am going to get shock collars, but I don't know what to do. I am so ticked. Any advice? My kids really want these dogs, but I am about ready to shoot them. They are 1/2 dalmation 1/2 english setters.
