Two nights ago I was lying in bed and heard a little noise in the yard. It was a bit windy so I didn't think much of it. About 5 minutes later I heard a sound that could best be described as a cat being strangled and then a bunch of squawking. I remembered then that I didn't shut the coop door. I jumped out of bed and grabbed the pellet gun by the back door. I went outside but couldn't see much so I called to my wife to get a lantern. In the mean-time I heard more squawking and weird sounds and could only assume that the chickens (I only have 3 at the moment) were being torn apart. Well, when my wife brought out the lantern and I looked into the coop, I saw a raccoon up in the corner of the coop, and my chicken were all yelling at it and flying about the coop. *WARNING* ANIMAL CARNAGE BELOW (No pics, just description) I shot the raccoon in the head from ~2 ft away with hollow-point pellets from my 1200 fps gun. It took 3 shots before it even moved, then it scampered out of the coop, and I got it one more time. That thing must have a skull of steel. Anyhow, it ran off into the darkness and the next morning I located it still in the backyard under a bush. Thankfully it was garbage day. Saved me the hassle of digging a hole. I was surprised that none of the chickens were injured at all. Not a drop of blood anywhere. I suppose that because the roost is several feet away from the door to the coop and entering the coop requires climbing up a trapdoor, that the chickens might have heard the raccoon and sounded the alarm. Regardless, they put up a good fight. tl;dr: Shut the coop door!
