Any studies on "resting" shipped eggs?

[underground chickenman]

I posted this in "quail" yesterday, but received no replies, so I thought I would try it here.

I am going to be receiving 100 coturnix hatching eggs on a Wednesday. I would like to time a hatch on the weekend, but that means I will have to put them straight in the incubator upon receipt, and even then hope for a textbook 17-18 day hatch. I have read many, many places, including on this forum where shipped eggs should be "rested" for anywhere from 6 to 48 hours. Are there any actual studies on this, or is all the evidence anecdotal? On the anecdotal side, have any of you experienced any differences between resting and not resting hatching eggs before incubating? Quail, in particular?

Thanks in advance.

some believe that if you "rest" the eggs you can cause the air sac to reattach had it been detached while shipping. I have tried this as I inspect my eggs when they arrive. I have yet to have ANY reattach. I let mine set for a few hours just so they get to room temperature and then put them in the bator. I think the ones that are believed to "reattach" weren't really detached completely but just partially down the side(I have had these hatch no problem). I personally don't think letting them rest longer than necessary(for temp reasons) is good for them as they are aging..... just my 2cents

Before I knew to let them rest I put them straight in the bator from the box and had good hatch rates...normal hatch rates for shipped eggs anyway. It comes down to personal preferrence more than scientific reasoning IMO. I don't think they'd reattach anyway.
