A little over a month ago I had some of my bird free ranging in my yard. We went to get a Christmas tree in the afternoon and were gone awhile. I didn't check the chickens at night with an automatic door opener, they take care of themselves. The next morning I noticed that most of the birds that I let out the day before were missing, nine of them, then I looked in our large garden and I found all of them laying dead in various parts of the garden with broken necks. I told my story to my neighbors who all raise chickens, telling them it sounds like a dog on the loose. One neighbor said he thought it might be coyote. My question is, do coyotes kill like that? I figured they would catch an animal to eat. All my birds, dead and alive, are accounted for, none were eaten. With winter set in the rest of my chickens are staying in the coops so they're safe for now. Come spring I like to know what kind of predator I'm dealing with.
