I was collecting eggs from my Australorps to hatch along with some BBS Orpingtons I ordered. And stupid me, I left several of the eggs bottom side down in the carton. Is it too late to save the eggs from the last two days? I figure the others are beyond worrying about.
They might all still be okay. Eggs and chicks are often a LOT more resilient than we give them credit for. I've successfully hatched eggs that were in the fridge for 16 days. Toss them all in the 'bator, and watch for development.
