Are Fertilized eggs healthier?
Information. There is no nutritional difference in fertilized eggs and infertile eggs. Most eggs sold today are infertile; roosters are not housed with the laying hens. If the eggs are fertile and cell development is detected during the candling process, they are removed from commerce.
How do you tell if an egg is fertilized without cracking it?

How long are fertilized eggs good for?
Therefore, do not store eggs more than 7 days before incubating. After 3 weeks of storage, hatchability drops to almost zero. Plan ahead and have a regular hatching schedule to avoid storage problems and reduced hatches.
Do eggs move before they hatch?
When Do Chicken Eggs Start Moving? Seeing an egg moving is also an indication that everything is going well and the chick is developing. In my experience, some eggs will start to move, which is more of a rocking motion, around 4-5 days before hatching.
