Something is killing my chickens, dragging them into the woods, but not eating them! Whatever it is, it has taken two both times, during broad daylight. It happened quick too. Left home for less than hour. Immediately searched, first time only found one, second time found both, literally in opposite directions well into the woods. We are surrounded on three sides by woods. No dogs come on our property, as we have a golden retriever. She was inside both times. Am I interrupting it each time before it dines? What is it?
