It's been dark here for a few hours but I just went outside to close to chicken coop doors because I was late getting home and my husband forgot (although the chickens are my responsibility and not his). I turned on the outside lights and can usually see inside our chicken coop but didn't this time. I found that 11 of the hens are missing! I found one hen with a missing wing and and a single head with the neck still atttached. Both of these were outside of the coop. I could see no other signs of attack or fighting, no feathers or anything. I suspect something got them while they were sleeping, but what would disappear with 11? I totally blame myself and now more than half of our flock is gone. We've never had a predator problem before, after 2 years of keeping chickens for nearly 3 years. I don't really suspect a dog as our neighborhood is pretty much dog free and I think that our dog who useless when it comes to protection would have at least showed an interest in another dog.
