Something killed 26 of my chickens - about 3-4 months old. It was so hot yesterday that we left the chicken door open as we were afraid it would get too hot in the chicken coop. The door opened into the chicken pen which is fenced. Obviously this was a huge mistake. Sometime during the night - we live in rural Ohio - the chickens were killed. 22 were left in the barn. They were found as follows: None were dead in the barn - all were dragged out through the chicken fence and under the fence which was pushed up quite a bit - it looked like 14 just fell over randomly throughout the woods scattered within about 50 -100 feet of the chicken barn. There wasn't a mark on them and obviously a few had their necks broken (I assume all). I found feathers where I assume one was eaten and the other 11 are completely gone. It is very dry and there are no tracks - it looked like whatever it was (or more than 1 thing) killed for fun but still managed to eat 11 (which makes me think there was more than 1 as I assume 11 is a lot to eat for anything?) We walked a good distance around the coop and didn't find a single feather out side of the 'kill zone'. Any ideas? This all occured in a horse pasture (where our coop/barn is). I know it wouldn't have happened had I shut the door (won't leave it open again) but I would still like to know what it was that killed them. We do have a stream about 100 feet from the barn - so maybe some sort of weasel/fisher? There are also a lot of trees around. However all of these chickens free range and we have never had a problem with anything getting them during the day and we have had them for 4-5 years. Any input would be great. Thank you.
