Dogs, dogs dogs, are usually the culprit. Have a neighbor that HAD a chow type dog that got into my other neighbor's chicken coops and killed all their chickens. They went to court and got that dog taken away, so she gets a freaking half pit that now barks at me and growls at me when I am on my front porch, getting out of my car, in my back yard etc...
It is driving me nuts. I am having a talk with her this weekend and if that doesn't work I don't know what to do as I love dogs, but this thing is pushing its luck.
