I have found two hens dead in the past several months, the latest just today. Both were found lying inside their coop in the same location and the same position looking like they suddenly expired. Both hens were previously healthy and laying well. Neither hen showed any signs of injury. My hens are housed with a rooster. Can a rooster possibly suffocate a hen while trying to mate? That's the only explanation that I've been able to come up with for the sudden deaths of these hens.
