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.
Does moving the egg during candling damage it?
And candling does not harm your eggs. Just as the mother would naturally leave the nest for a short time each day, you can safely take your incubating eggs out of the incubator for the few times you will be candling them.
What happens on day 13 of hatching a chick?
What is this? The inner eyelid and the egg tooth, which the chick will eventually use to peck her way out of the egg, are also forming.
How do you tell if your 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.
What will you see when you candle a fertile egg?
To know if the egg is a winner look for a network of blood vessels that appear white. A dark outline at the center of the blood vessels is the embryo. You may even see the dark eyes of the embryo or the embryo moving slightly. These are both telltale signs that the egg is a winner.
Can you candle an egg too much?
Over-handling, e.g. over-candling, will increase the potential of an egg getting contaminated from dirty hands, a sneeze or anything else! Contaminated egg shells create dead chicks or an egg that could explode in the incubator!
Can it take longer than 21 days for eggs to hatch?
Incubating large breed chicken eggs usually takes 21 days. Bantam sized are more likely to hatch around day 19 or 20. However, this can vary depending on various things, most importantly the temperature levels in the incubator. If the temperature drops for any reason, the hatch will take longer.
How do you tell if a chick is still alive in the egg?

How long after incubation can you candle eggs?
I recommend candling chicken and duck eggs after 7 days of incubation and again at 14 days. After a week of incubation, you can be reasonably precise about the viability of the embryo. At 14 days, you can remove any eggs with embryos that have died and lessen the risk of a rotten egg exploding.
When to remove non-viable eggs from candling eggs?
For the 7 and 14 days candling eggs photos I show in this guide (to remove non-viable eggs), and a successful hatch, we only really need to consider two high-risk periods for embryo death: At the beginning of incubation and just before the chicks hatch.
How long does it take for egg candling to work?
First candling: 7 days After a week of incubation, place your egg onto your egg candler in a darkened room and turn on the candling light. You should be able to see shadows from inside the egg.
