I've posted here before about finding a hen dead in the coop with no signs of predation or mites. Always fine without signs of illness. It happens every 1 to 2 months and I've lost 7 hens in the past 8 months. Yesterday I collected eggs at 7pm while the girls were out free ranging and everyone appeared fine. They went in the coop about 7:45 and I went to lock them in, found another one dead under the roost. Every single one I have found has been under the roost in the same spot. Do they fall off and break their necks? It just seems too coincidental! These are all about 1 yr old now. Just confusing!
