could somebody put me onto an article or answer the following questions 
prompted by white plumed honeyeater building nest in our yard.

1. I understand length of day stimulates sperm production in male(?).  Is this 
the same for eggs in female-would eggs be produced irrespective whether she 
mated?  If she didn't mate, would they just be voided?
2. Is nest built before courtship?  Before copulation?  I am guessing 
courtship, nest, copulation would be the order of the day
3. I gather there would be the necessary numbers of eggs in different stages of 
development within the female.  Are they soft shelled until the last minute 
allowing fertilisation or how does this work?  Do the eggs only harden as part 
of the birth process?
4.  What is the gap between eggs in a bird like white plumed honeyeater and if 
they wait to start brooding until all eggs are laid, do  they not die because 
they haven't started changing from egg to bird?

Thanks for your help
