Thanks for the good information, but what happened to your chicks? Any
survive and leave?

Unfortunately I don't know, but I suspect not. I haven't emptied the nest
yet to see how many corpses there are, and in any case the parents try to
remove early dead chicks as part of their hygiene regime. There had been
eight eggs...

In previous years chicks had left the box too early (it seemed to me) so I
picked them up and put them back in an attempt to keep them away from the
multiple predators around here until they had a better chance of flying to
safety. But I don't think it works...
