Turning the eggs in your incubator is one of the most important parts of incubating. The hatch rate can significantly decrease if you do not adequately invest in the time to turn your eggs every day for the first two weeks or so of incubation.
So, why do eggs need to be turned in an incubator? Eggs need to be turned inside the
Proper Embryo Proper Development
There are a few reasons, and they all have to do with the proper development of the embryo. They also have to do with the proper development of the internal workings of the eggs that nourish the embryo. You can turn your eggs a few times a day by hand or have an incubator that self-turns your eggs at a given interval over the day.
Either way, you must turn your incubating eggs. Otherwise, it’ll affect the hatch rate and the health of the chicks that do hatch.
I’ll address several important reasons why eggs need to be turned into an

Properly incubating eggs can be a lot of work, but your chicks will be very grateful that you put all that work in once they’ve hatched, nice, and healthy.
Why Do Chicken Eggs Need To Be Turned?
There are a few reasons why it is important to routinely turn your chicken eggs during incubation. They all have to do with not keeping the embryo in one place for too long. This is done both so that the embryo grows correctly and so that the internal workings of the egg grow correctly.
If the embryo stays in one position, then it will not grow as strongly due to one side being favored in growth. The embryo should also ideally be rested on the yolk. The embryo can often get stuck between the wrong side of the yolk and the shell if you don’t turn your eggs.
This results in the embryo and the yolk being at risk for damage or improper development. The embryo is also likely to get stuck to one side of the membrane inside the shell.
You want every part of the embryo and every part of the internal workings of the eggs to be able to breathe and move. Turning the eggs increases the development of the vein network. The vein network is responsible for carrying oxygen and nutrients to the embryo.
Turning also promotes the growth of the yolk and allows the embryo to get into the proper position for hatching.
What Happens If Incubated Eggs Aren’t Turned?
You will run into many issues if you don’t turn your eggs properly in the incubator. First of all, the chicks will have a hard time hatching.
They will likely be stuck to one side of the egg during growth. The embryo getting stuck to one side of the egg can lead to deformity and sometimes even death. If eggs are not properly turned, the average hatch rate can drop by as much as 30% (1).
Even if your chick manages to come out of the shell without any problems, they likely won’t be as healthy as if you had turned the eggs. Not turning the eggs means the internal workings of the egg don’t develop as freely as they should. This can lead to the embryos not getting enough oxygen and nutrients. You may notice that the chicks that hatch are slightly sickly if this is the case.
Eggs can be turned either by a machine or by hand. Many people don’t want to pay for a machine that will turn their eggs for them. You should definitely be sure that you are turning your eggs by hand if this is the case.
Turning the eggs is incredibly important to the overall health of the chicks, and it’s not that hard to turn the eggs by hand at least a few times per day.
How Often Do I Turn the Eggs In My Incubator ?
Firstly, leaving the eggs to settle for about half a day after placing them in the
This allows time for the eggs to settle internally and for the embryos to get comfortable. You will begin your turning routine once this time has elapsed. It is advised that you turn your eggs at least three times a day, though ideally more like 5 times a day.
Many people believe you should make sure that you turn the eggs an odd number of times per day compared to even. This ensures that the embryo never rests on the same side of the egg two nights in a row.
This will mainly be an issue if you turn the egg by hand only a few times per day, such as 3. Odd numbers going up from 3 would be 5, 7, 9, 11, etc.
Another common trick to ensure that the eggs never rest on the same side two nights in a row is to mark their resting place with a pencil on the shell. Make a mark and then ensure that the mark is never facing down two nights in a row.
The first week or so is the most critical time for turning the eggs. You want to invest plenty of energy to ensure you turn your eggs enough, especially in that first week.
The second week is still important, but you will be better off missing a few turns the second week than the first.
Some commercial egg operations will turn their eggs once an hour and generally use a machine that automatically turns the eggs every hour. Turning your eggs once an hour isn’t going to be totally necessary or even feasible if you’re turning your eggs by hand. Still, you should try to aim for it at least 5 times a day and always remember to keep it at an odd number.
You should generally turn the eggs about 45 degrees each time. Turning too much or too little runs the risk of decreasing the hatch rate. It is also not advised to turn the eggs continuously. Continual turning results in the egg being unable to settle and can lead to the yolk rupturing.
What Day Do You Stop Turning Chicken Eggs?
It is generally said that you can stop worrying about turning your eggs in the incubator about two to a half weeks after placing them. So, generally, it is about 14 to 18 days, with most people going closer to 18 days than 14.
Ceasing to turn the eggs allows for better airflow and heat transfer from the embryo. This results in a more stable temperature for the embryo in a few days before hatching. You should have the egg placed with the larger end if the egg is placed vertically in the
This will allow for the best positioning of the embryo before hatching. Simply laying the eggs flat will be fine if they are placed horizontally.
Eggs typically start hatching at around 21 days, but don’t be surprised if it takes just a few days longer. Patience is key as far as growing chicks. Never be disturbed if they aren’t hatching as fast as you’d like. Things should go smoothly if you’ve done everything right in the weeks leading up to hatching.
Resist the urge to continually turn the eggs if they aren’t hatching on time. Turning the eggs this late in the game can cause the chicks to be moved from their ideal hatching position and offer no benefits.
Sit tight and wait for the chicks to hatch, and rest assured that you’ve done as much as possible.
The hatch rate on eggs from your chickens is generally around 80%, or 50%, if the eggs have been shipped or purchased elsewhere.
This rate shouldn’t be negatively affected if you’ve properly turned your eggs at least 5 times a day for the first two to two and a half weeks. Don’t get too bent out of shape if things don’t go perfectly. Some trial and error will always be involved when it’s your first time.
You will develop a workflow as you continue hatching that will enable you to find the best times to turn the eggs into your daily routine. In general, the more you turn the eggs, the better!
