Collecting eggs: when's best?

[Nicholas Baggott]

We've been doing a lot of microinjections and have gotten to the point
where a limiting factor is egg availablity.  Could anyone send me a
reference or give me advice on factors that affect egg laying.  I'm
especially interested in knowing what time of the light-dark cycle is best
for collecting fresh eggs.


Thanks,
