Try not to store eggs more than 7 days before incubating. A 14 day storage reduces hatch to near 50% and after 3 weeks of storage, hatchability drops to almost zero.Plan ahead and have a regular hatching schedule to avoid storage problems and reduced hatch percentages.early all fertilized chicken eggs will hatch after 21 days of good conditions - 99.5F Â°(37.5 Â°C) Eggs must be turned regularly (usually three to eight times each week) duri â¦ ng the first part of the incubation.
