So when I went to collect eggs yesterday late afternoon after getting home from work, I saw one of my two BR hens laying just inside the coop. I knew immediately that this was not OK. One hen has been broody and sitting in a chicken nest box in approximately the same spot and she is doing fine. I went inside the run to get a better look and she was just laying there, not bleeding, but pecked at on her back and dead. I had to call my FIL to come get her out as hubby was working the night shift and had too many calls backed up. He got her out and looked her over. No gashes or bleeding. She was right next to the nest boxes and the position she was in leads me to believe that it likely wasn't that the tom mounted her and accidentally broke her neck or anything. What the heck happened???? She was completely fine the evening before, no signs of a fight. She was just around a year old and my much better layer! UGH!
