Found one of my EE hens dead in the pen yesterday. One year old. Not a mark on her and I had not noticed any signs of illness. It's been hot here but really not bad at all compared to most summers. I'm wondering if her neck was broken because the body was in rigor but her neck was extremely floppy. My hens get the skitters sometimes like cats do who go racing through the house for no reason. So she could have taken a sudden running flight and smacked into the fence, or roost, or something else in the pen. But I know they just drop dead sometimes. Had one do that last year in the coop.
