I've always collected a lot data about my settings in the hopes that one day something will pop out at me as miraculous...alas, not yet. But I did add one new dataset in today's setting. I recorded each egg's weight (in grams, to 2 decimal places with a jewelers scale) at the time I took them out of the nesting boxes. Then today, while setting them, I re-weighed each egg. As expected, the older the egg the greater the difference (original versus setting weights).
The daily weight loss is about 1/3 what is expected during incubation; in the worst case an 11 day old egg had lost 2.12% already.
In my last setting, I had equally old eggs, stored the same way as these, so they probably had the same weight loss prior to setting. It didn't seem to affect the hatch, old and new eggs hatched on the same day (not all on the same day, but each day there were old and new hatching).
I'm thinking its not good to lose that much weight prior to setting, so perhaps storing them in a cooler with a damp cloth might create high enough humidity to reduce the weight loss dramatically. Can an egg gain weight due to excessive humidity?
