How long can you store them in the fridge before trying to hatch?

Honestly after 3 to 4 days you would be pushing it. I have had an egg that was in the fridge for 2 weeks hatch, but when you wait so long, you can theoretically set yourself up for nasty problems. The longer they are in the fridge, the less likely they are to develop, and the more likely defects or problems may occur in the hatch.
