It's so difficult to tell why birds die without an autopsy. It's even hard to tell when they're close to dying, they're so good at masking their illnesses. It sounds like maybe the hen had reproductive issues. And possibly the cockerel a heart problem if he looked purple.
I have had several sudden deaths in my flock this spring and summer, some birds were eating out of my hand only to be found dead the next day. It does not appear to be Mareks and they don't show any signs of illness prior to dying, and no signs of illness in the flock, as you would expect from AI. It is a mystery.
