Can I candle eggs on day 17?
Day 17 is the last time that the eggs need to be candled. You need to remove any obvious early deaths and leave all the rest. There is not much to see in a Day 17 egg, all you should see is the air cell (which will be a lot bigger that it was originally) and most the rest of the egg should be dark.
Do eggs get lighter before they hatch?
The initial high correlation between egg weight and chick weight decreased markedly during post-hatching growth, becoming insignificant 5 d after hatching. At 18 d of age, however, chicks from eggs of older hens tended to be heavier than those from younger birds.
When should I stop candling my eggs?
Normal Development of Eggs * As the hatch progresses the air pocket in the egg should be getting larger and the egg will be getting darker as it is filled with more bird. * During the last 3 days of a hatch, it is best to avoid candling the eggs unless you have a specific reason to.

Many people find that hand turning every 6 to 8 hours to be the “sweet spot.” If you do not turn the eggs, the tiny embryo can stick to the shell membrane and may die. During the first 17 days, you will also monitor the temperature and humidity, adding water to the water reservoir as necessary to maintain the humidity.

How do you tell if an egg has died?
You’ll see blood pumping through the heart of a tiny, developing embryo if you candle a fertile egg on Day 4. If the embryo dies at this point, you may still see a faint network of blood vessels inside the egg’s contents. An embryo dying at this point will show a large, black eye.
