- First, position the egg directly from the light source.
- The bulb, or in case of a flashlight, you will only need to switch it once the egg is in position. If you are using a torch the hole should be enough to hold an egg. However, you can choose to hold the egg yourself; it is also okay. This process should take place in a dark room for the best results.
- Switch on the light directing through the egg.

Day 4 egg candling
If the egg has a healthy embryo, you should be able to see a spot like in the egg with vein-like branches originating from it. The embryo might not have developed well, unfortunately. To know this, you will see a ring of blood around the egg. This calls for the alarm to remove the egg immediately. If you see nothing, then this means that the egg is infertile and there is no embryo.
At this stage, the spot should have grown larger, this means the embryo is developing. If you see a blood ring round the egg, then the embryo did not survive, and you need to remove it.
At this stage, most eggs will have grown darker. You should still be able to see the veins and the large spot. The embryo has now grown near completion. Any bad smell or blood ring round the egg, calls for the alarm to remove the egg.

You might detach the fragile air cells
Some egg candlers are specially designed to turn the egg without the farmer touching it. If you keep on touching the egg in the name of candling, you might end up clogging the fragile air cells. This will cause great damage to the egg. No matter how gentle you try to be with the eggs, you will always end up detaching and blocking the air cells.
You will contaminate the eggs
It always advisable to hold the eggs using clean hands. Doing it so often, you might forget washing your hands before touching the eggs. Contaminated eggs hatch dead chicks or the egg might even burst while in the incubator. Whenever you smell a foul smell from the eggs, smell all eggs one by one and remove the bad one from the rest. You might feel the smell from a distance. This process is important.
You might drop fertile eggs
Eggs are super fragile, a slight hit on its shell and it becomes useless instantly. It is so sad if you drop an egg even when it was for cooking, imagine that feeling when the egg was destined to hatch. This gets worse when you drop the egg you were candling under the other eggs below it. The eggs might not break but, the air pores might block, or the egg will be contaminated. Such accidents cause huge damages and must be avoided as much as possible.
You might lose the heat and humidity of your incubator.
Keeping the heat and humidity of an incubator intact might be very tricky a number of times. Therefore, reduce the number of times you candle in turn reduce how many times you are in the incubator. This helps keep the humidity and heat intact. This is very important, regarding the fact that without paying much attention to it might damage all your eggs.
What are Important things to note when egg candling?
Why are you candling?
The first thing is to understand why you are candling in the first place. If you are candling from home, it is important to keep track on the embryo and general development of the eggs. When hatching eggs from home, it’s very rear to get 100% hatch success. Not all eggs will hatch. Some will be infertile; others will just get damaged.
It is important to identify the yolkers and the quiltters earlier. If not, they will rot and burst inside the incubator.
What kind of equipment do you have?
A candling equipment does not have to be fancy to bring the best results. In fact, back in the days as we earlier said they used candle flames. The main requirement is light with high intensity, a place to put the egg plus a dark room. You can use a flashlight, make your own egg candler or use any of the best reviewed candlers above.
What procedure should you use?
You should candle your eggs before putting them in the incubator. Probably you will not see anything, let alone being able to differentiate between the good and the bad eggs.
It will also help to look for tiny cracks around the eggs shells. Cracked shells are more susceptible to bacteria, it will get inside and damage the embryo. If you find a cracked egg do not discard it yet, put a mark on it and monitor its progress.
In general candling of eggs is done to determine the state of the air cells, the yolk, and albumen of the egg. Candling also helps you spot bloody albumens, meat spots, or even blood spots, and it allows observation of any germs that might be developing. Candling should be done in dark rooms with light flashed through the egg. The light passes through the eggs shell and lets you observe through the inside.
The egg candler should be placed on top a table or a box at a height that is convenient and favors you 38-40 inches from the floor is advisable, this will not let the light shine into your eyes directly. In handling, the egg is held in a slanting position with the large end of the hole in the candler. The egg is then grasped or maintained by the sharp end, and while also held in between your thumb and the tips of your first two fingers, is turned quickly to the right or left. This lets the egg contents move and also moves the yolk nearer to the shell. Due to the color of their shells, brown eggs are harder to candle than white shelled eggs.
So as to do work with good results, extensive knowledge of candling is not necessary, mainly if the eggs are all fresh. You should be able to differentiate a fresh egg from a stale one and detect such abnormalities as bloody whites, blood spots, meat spots, and cracked shells. In a fresh egg, the airspace is plainly visible and moves freely. The white is thin and clear. In a stale egg, the airspace is plainly visible and moves freely. The white is thin.
Mostly newly laid eggs are often of high quality. Eggs that are not over two to three days old, if put under suitable conditions, will meet the specifications the best classification which is Grade A. the eggs that should be removed are the ones with meaty spots, blood spots or white spots on the shells.
How do I candle incubated eggs?
As discussed earlier, candling incubated eggs should be done with so much care. They are candled to determine if they are fertile and, if productive, to see and monitor growth and development of the eggs embryo. White eggs should be tested for productivity on the third day while brown shelled eggs should be tested on the fifth or sixth day because it is tricky to see the embryo clearly before this time.
A small reddish area with blood vessels extending away from it will be visible in fertile eggs. This is the embryo floating around inside the egg, looking like a vast red spider. If the embryo dies, the blood draws away from the embryo and forms what is called a blood ring. All clear eggs and eggs showing blood rings or streaks should be removed from the incubator. If eggs aren’t candled during the early stages of incubation, it will be hard to determine whether the egg was fertile; embryos that die early soon decompose and are not easily differentiated from rotten eggs.
