I'm glad they made safe. I hate how post office don't update till they get delivered. I bought thing to candle my eggs off eBay. And it makes candling brown eggs easier. As far as letting them set I've heard some say 8 hours some say overnight. One of my sets I got this swap I only let set like 4 hours and I think 4 or 5 are showing good signs of life. As long as they accheive room temp they should be fine.
