Last summer we lost all four of our hens and a rooster. Something cut the heads off and left them all dead in their pen over a three day period. We reinforced the enclosure and this spring we got five more. They've been out in the enclosure and coop for about a week (finally out of my garage) and this morning three were missing. I found a single head about a yard outside their enclosure. We have completely redesigned the coop. What on earth is getting them? It rained pretty hard last night but I can't see any evidence of anything getting in. There is about a six inch gap between the chicken wire and the top of the enclosure (which has a tin roof). We're going to close that up this afternoon. But what on earth could be getting them? Oh, we live in the middle of a pretty small town. We have a huge owl who resides in one of our big oaks in the back (hence the tin roof on the chicken enclosure). But all we've ever caught in our traps are squirrls. What could be getting them?
