I use to own a husky, I know what they are capable of. I walked him three times a day seven days a week (we had a small yard at the time). He was always full of energy and could get into the darndest things. But I knew what my responsibilties were going to be when I got him. He could still pull stunts at 14y/o and to this day I cant figure out how he accomplished some of them. These neighbors are slackers and do not seem to care about any of their animals. I'm glad you have a sheriff who is willing to do that for you, ours would say just shoot it. I wish I were closer I'd rehome it for you. I'm glad to hear your hens are okay.
