Blue Tit

I have a nest box on the side of the house with a resident Blue tit which made the nest and started laying. About 6 eggs are present. In the box is a camera which many of my friends are watching with excitement.

Sadly this morning I witnessed the mother looking in some distress on her own in the nest and then within 2 minutes she went on to her side and is clearly dead. I suspect it could be egg binding as it was early morning and no other birds were near.

So the question is what do I do now. I have disconnected the camera as I do not want the young children seeing the dead mother. I assume that the eggs will have to stay as is due to law not allowing the eggs to be moved till September. But do I have to leave the mother in the box??
