Came home from the grocery store to all my hens running free. I keep an old pallet leaned against the doorway to the coop to keep my sheep out of the coop, the pallet was right were I left it. Inside the coop I found the gate latch bent (door opened inward) and wide open. I found a decent amount of blood all over a nesting box, on the gate frame and spots of blood other places. All my birds are accounted for (thank God!) What on earth could it be? I thought dog, but the dog would have knocked over the pallet to get inside, then I thought cat but it's not strong enough to bend a gate latch? Then I though maybe a fox? But we recently had a fox attack on the property and he killed 6 birds in a matter of 30 minutes, so I don't think it was a fox. And I'm pretty sure it wasn't Cornell Mustard with the candlestick in the dinning room either. Any ideas?
