Yesterday, I found that something had killed 16 of my hens, and 5 are missing altogether. The ones that were killed were for the most part just mauled to death, and not eaten. Several of my remaining 20 chickens (17 hens and 3 roosters) are missing a lot of their feathers, but appear to be uninjured. The attack happened around 2pm on a sunny day. We have 14 acres, with the back part being partially wooded. I have seen coyotes, but nowhere near the front 3 acres where the chickens range during the day. The chicken's area is fenced with 4' no climb wire. The next door neighbor's dog has been in our pasture, but the chickens are fenced off of the pasture, and I've never seen the dog in the "yard". All they coyotes I have previously had experience with will grab what they can get and leave. I have never had one kill and leave a bunch of prey. I think it was the neighbor's dog, but my husband thinks it could be coyotes. Anyone else ever have coyotes go on a spree?
