What are you really asking? Is it possible? Will a refrigerated egg hatch as well as one that has not been refrigerated? Best practice is to store eggs for hatching at a coolish temp. Somewhere around 55 (based on my shabby memory!) would be ideal. Also, ideal would be that they be stored at around 50% humidity (again, based on my shabby memory) and turned several times/day like you would if you were incubating them. Also, they should be less than 10 days old, and clean, but not washed. Now, with all of that "they should be" and the "they say" done, I'll go on to say that there are folks who routinely hatch refrigerated eggs. They also have fair luck hatching eggs older than 10 days old, and they hatch eggs that have been washed or are dirty. Why there are even folks who go buy a dozen fertile refrigerated, older than 10 days old, washed eggs from Trader Joe's or Whole Foods, and they get chicks!
