Store these fertile eggs in a place where the temps are around 45-60 degrees. Some people store theirs in a refrigerator, but I have found that a fridge is a bit too cold. Maybe it's because my wife likes ours to be around 33 degrees. When we stored our fertiles at that temp, I lost about 50% of them. Since storing them in our unheated basement (around 50-55 degrees), our hatch rate has gone up a lot. Be sure to warm the eggs at room temp (around 70-75 degrees) before putting in the incubator. Good luck!
