Strange broody hen behaviour

[Spook241]

Sorry for your loss. Have you checked the nest site for a possible mite infestation? Sadly, it sometimes happens.

Thanks for all the messages, much appreciated.

Yea the nest looks absolutely fine, I have no idea what happened.

I had no incubator or anything to transfer the the eggs in to, so opened them to check what was actually happening. Looks like one probably would have made it to hatch.
