I am devistated. Every single one of my hens were slaughtered by some predator last night that got into their coop. I feel so horrible. I am posting this so others can learn from my mistake. They were in the type of coop with a run underneath it. I had boards that were buried in the ground around 6" down around the perimeter which I thought would deter digging in. I was wrong. All of my beautiful hens are dead. Luckily I still have the pullets that I just hatched out earlier this summer as they were in a seperate coop. But all of my lovely ladies that were so tame and ran to me for treats whenever I went outside are gone. I'm a horrible chicken mom. It was a small predator, the hole under the coop is only a few inches high. It got in and killed them all, didn't eat them. I'm not sure what it was. Please learn from this and don't let it happen to you I can't stop crying I feel so bad.
