I think it was last year that Purplechicken tried and experiment with hatching out some silkie eggs that had been refrigerated for awhile to see if it would work. I can't find the post, but I don't think they were in the fridge for very long, but I do remember being surprised that he got so many out of the hatch. A few days back, a predator got a hold of my precious Miss Cuckoo and Flo, leaving me with only 4 eggs collected in the past 3 days and 4 others that had been in the fridge for about a week, for a total of 7. They had been on the counter in my kitchen a few days before that, so I had my doubts, but decided to try anyway. I let them get to room temp, then stuck all the eggs in. I checked tonight, and 3 of the 4 fridge eggs are growing!! I'm just hoping they make it, and that at least one of them is a cuckoo!
