Once a dog gets the taste of blood there is no way to retrain it. Put it down. Sorry, but he will kill again and maybe get into other's chickens.Our single chick from the first clutch was doing great. Her name was Joy. Then our husky killed her. Our second clutch gave us 3 chicks. Stormy, Peekaboo, and the third has yet to be named. Our Malamute ate Peekaboo. I’d have rehomed them both by now if it weren’t for my wife’s intercession. So this happened. I’m not done yet, but this is what I got done today. It will require more posts and I need to move a couple as well. I really didn’t want to section off my backyard. But at this point I had no choice.
