first let me say how sorry I am that you are having to go through this. It is always hard to lose a chicken, for many of us they become important parts of our lives. Now, you say you aren't a great shot, and your neighbor has small children, and this bad boy knows when you are and aren't there. Bad enough he got your roo and went after you, but one has to draw the line when children are involved. Can you or your neighbor get a hold of a shotgun? This thing has to go. I know some people may feel differently, however, we need to consider how we would feel if he got you or your neighbor's kids. Or at least I would have to consider the kids, since wildlife/conservation won't do anything. You have tried to do the right thing and contact them, and have been left with no choice (you and your neighbors), but to handle the situation yourself. However you decide to handle it, good luck
