For those of you that have chickens, quails, ducks or other types of birds, you’re probably aware of the importance of having the right kind of equipment for hatching season. Female birds of all kinds are capable of laying eggs right after mating season, and it can be difficult to figure out what to do with all of the eggs that she lays.
If you want to make use of the entirety of your female birds’ egg-laying abilities, then you may want to consider purchasing an egg incubator. Egg incubators are devices that are capable of keeping the bird eggs alive and healthy throughout the beginning of their lives. They act as though the mother is sitting on them, helping them to increase the success of their hatch rate.
But there are so many different kinds of egg incubators on the market, making it difficult to choose the best one for your specific purposes. To be more helpful, here is a guide containing the best egg incubators on the market as well as some helpful information that you should consider before choosing a certain one for you.

Factors to Consider
If you do not have access to a broody hen and want to go with artificial egg incubation, then it is important to spend a little time working out the best incubator for your needs. There are a lot of incubators on the market for both the small backyard chicken keeper and bigger poultry operations. Here is a guide to help you understand some of the different types of incubators and the terms you will come across. You should of course have purchased your incubator before buying or acquiring your hatching eggs.
The Less you Pay for an Incubator the More Time You Spend
As a rule, the less you spend on an incubator the more time you will have to spend monitoring and aiding the incubation process. The cheapest incubators are the styrofoam models. These hold about 4 dozen eggs at a time, which is probably more than most backyard chicken keepers will need to set. However, these inexpensive incubators have manual temperature control, manual turning, and manual control of humidity. So you will really need to keep a constant eye on things and know exactly what you are doing. These incubators are usually bought by first-time hobbyists, who due to their lack of experience, tend to get very poor hatching results. Which can be expensive if the hatching eggs are rare breed ones. Of course, you can be very successful with these inexpensive incubators, but you must be prepared and understand how much time and effort it takes to get those results.
If you choose this type of incubator you must be prepared to be available for the whole 21 days the eggs takes to hatch. You will not be able to go out unless you recruit a replacement to take over from you. With a manual incubator, eggs will need to be turned by hand every few hours, at least three times a day. It should always be an odd number so that the eggs do not rest the same way two nights in a row. You will have to monitor humidity and adjust the temperature precisely throughout the day. If you forget chances are you will lose all the embryos.
Still Air or Forced Air Incubators
You will see the terms still air and forced air incubators, the difference is simply a fan. In the forced air incubator, a fan circulates the air around the incubator, thereby keeping the temperature constant in all parts of the incubator. The temperature can be measured anywhere within the airflow. In a still air incubator, there is no fan, and the heat forms layers inside the incubator, making the temperature difference between the top and bottom of the incubator.
Care has to be taken when setting the incubator up, the temperature at the center of the egg should be correct for the species of bird being incubated. It is usual to measure the temperature at the top of the hatching egg, with a correction made to this according to the manufacturer’s guidelines.
Minor Upgrades to the Basic Incubator
Every little bit helps when it comes to adding on to basic incubators. For example, styrofoam incubators can be purchased with an egg turner and a fan. This makes things much easier as egg turning is handled automatically. Measuring temperature will be easier as it will be more constant throughout as the fan circulates the heat so that the temperature can be measured anywhere and you will not get the hot and cold spots you do with a still air incubator. However, temperature and humidity control are still manual on these incubators.
Fully Automatic Incubator
With a fully automatic incubation, you can simply set your eggs and let the unit get on with things. These incubators control the temperature with no input from you. Some of the more expensive ones control humidity as well, while others at least provide a built-in hygrometer (an instrument that measures humidity) so you can more easily monitor what is going on. Automatic incubators will turn the eggs on their own and count down to hatch day and automatically stop turning on day 18. Obviously, these are more expensive but if you are going to be hatching lots of eggs then it will be a good investment.
If you are prepared and able to devote the time and effort for 21 days, a manual incubator will work very well for you. However, if you are not able to do this then you should choose an incubator with as many automatic controls as you can afford.

Incubating your Poultry Eggs
Caring for Eggs Pre-incubation
It is a common assumption that hatching eggs should be put straight into an incubator as soon as they arrive in the post or as soon as you collect them from the hen, or else they will go off. This is not true and in fact by doing so you will actually be reducing your chances of hatching the eggs successfully.
Especially if the eggs for hatching have been shipped to you it is extremely important to place the large end up in a clean egg carton. This will allow their air bubbles to stabilize and move back to their proper places at the large end of the egg. For best results, you should leave the eggs to stabilize for about twelve hours. Eggs should always be stored with the pointed end pointing downwards as the egg is actually damaged if it is stored with the round end down for any length of time.
However, you should not store the eggs for more than 7 days (in total so be aware of the age of your eggs on delivery) after they have been laid as hatchability reduces significantly thereafter. Eggs should always be stored in a cool area that is slightly humid and definitely away from sunlight. Again they must be stored with the pointed end down.
You should also turn the eggs regularly while they are being stored, as well as during the incubation period. You can do this in the morning and evening, a simple way to do it is to tilt the egg boxes in a different direction each time. Incubation time. You can do it in the morning and evening, the simple way to do it is to tilt the egg boxes in a different direction each time.
Prepare your poultry eggs for incubation
A lot of people imagine that it is essential to get eggs for hatching into the incubator as soon as you get hold of them. However, this is not correct, especially if they have been shipped to you, as even with the best carriers the eggs will have been shaken about a bit during the journey. Therefore it is essential that you allow the eggs for hatching to stabilize. You should therefore place your hatching eggs large end up in a clean egg carton, which will allow their air bubbles to move back in place at the large end of the egg. For best results, leave them to stabilize for about twelve hours. Ideally, they should be kept in a room where the temperature is around 50o F (10 C) and the relative humidity is 70 to 80 percent. If the temperatures are below 40o F (4 C) this is likely to reduce hatchability. Most normal room temperatures will be too hot and it is worth noting that embryos will begin to develop at subnormal rates when the temperature reaches about 80o F (27 C) and will not survive.
Prepare your incubator properly
While the hatching eggs are stabilizing you should set up your incubator and get it running at the correct temperature and humidity before placing the eggs inside. It is essential that the temperature is correct before the eggs go in. If the incubator does not come with an accurate thermometer then you will need to purchase one separately, the same goes for a hygrometer (which measures the humidity).
Your incubator should be set up ideally in a room in which the temperature is between 70o and 75o F (21 and 24 C), and which is free from drafts and excessive variations in temperature, so be careful with radiators or similar heating. Do not place the incubator near windows or where it will be exposed to the direct rays of the sun, as the sun’s rays may raise the temperature so much that the eggs will be cooked.
Adding the poultry eggs
The temperature will immediately drop when you add the eggs, not just because you have opened the lid but because the eggs will be a good twenty degrees cooler than the inside of the incubator. However DO NOT adjust the thermostat to compensate, as if you are using a manual incubator you may well finish up cooking the eggs. Wait instead for about four hours and if the temperature is still low make as tiny an adjustment as you can manage and watch for a while to check it has not made it too hot. This is especially important if you are using one of the popular manual styrofoam incubators where the smallest of adjustments can make a large change. Automatic incubators will adjust and monitor the temperature for you.
Eggs must be turned while in the incubator, so before you put in the eggs mark them with a pencil so you can tell when they have been properly turned. If you have an incubator with an automatic turner this will be done for you. An excellent method is to put an X on one side of the egg and an 0 on the opposite side. Then you can always tell when the eggs have been turned because either all ’0′ ‘s or all ‘X”s will be facing up at the same time.
The Importance of a good thermometer and hygrometer
As noted above it can be difficult to get temperature right with some of the manual incubators, so a good thermometer is essential. Most cheaper incubators come with a small thermometer but we recommend that you use a second one just to be sure, as thermometers can vary greatly in inaccuracy. If you do not have a hygrometer it might be a good idea to get a thermometer/hygrometer combination, since humidity levels are also vital for successful hatching. If humidity is too high, the chicks can drown when they try to pip the shell. If it is too low, they can get stuck to the egg membrane, effectively shrink-wrapped and trapped inside the egg.
A temperature of just one degree out can cause your eggs to fail to hatch, or if they do hatch the chicks will be very frail and may not survive. However, don’t worry if the temperature is not correct for a few hours you should get away with this.
N.B If during incubation you notice a bad smell coming from your eggs, find the bad egg, and remove it quickly before it explodes and contaminates the others and your incubator.
Quick Tips for Hatching Poultry Eggs
Here are some quick tips for getting the best results when incubating and hatching poultry eggs.
Incubate or set at least six eggs
Don’t set or try to incubate less than six eggs at a time. You are unlikely to have a 100% hatching rate, in fact if they are shipped it may be as low as 50%. You may finish up hatching only one chick and since chickens are flock animals they need others around them or they will be miserable and can even die of loneliness. Remember that half or more of those hatched may be males, which may not be what you want.
Make sure the incubator is at the right temperature and humidity levels are correct
Plug your incubator in before putting your eggs in and ensure that it reaches a steady 99.5 degrees fahrenheit (37.5 centigrade) if it is a forced-air incubator, or 101.5 degrees (39.2 centigrade) if it is a still-air incubator. Still-air incubator temperature needs to be higher because the non-moving air inside the incubator rests in layers, which will be cooler at the bottom of the incubator and warmer at the top. You should use a thermometer and a hygrometer (which measures humidity) if your incubator does not have ones built-in. Always measure the temperature at the top of the egg. Humidity should be 45-50% for days 1-18, then 70-80% for the last few days. However always read the instructions that come with your incubator.
Open the incubator as little as possible
Try not to be tempted to open your incubator as warmth is quickly lost and it should be especially avoided during hatching. Opening the incubator during hatching will also let out humidity and increase the chances that late hatchers will get stuck to the shell and be unable to escape.
Mark and turn your eggs
Eggs should be turned at least three times a day, always an odd number of times, otherwise they will not hatch or you will get deformed chickens. Mark eggs, using a pencil, with an X on one side as it is easy to lose track of which have been turned. Obviously if you have an incubator with an automatic turner so much the better. Hands should always be clean before touching eggs to avoid transferring bacteria.
Eggs should only be turned up to day 18, after that they should be left to allow the chick to position itself properly for hatching.
When eggs for hatching are put in the incubator,they should be laid on their sides and turned at least three times a day. Turning prevents the embryo from sticking to the shell membrane as it will do if it is left in one position for too long. Good results can be obtained by turning the eggs first thing in the morning, then again just after noon and last thing at night. However ideally you would turn your eggs more than three times a day. If you buy an incubator with an automatic turning mechanism this will be done for you and save you a lot of time. If you work full-time away from home you will have to use an automatic egg turner, or if you expect to be away from home for more than a few hours during the first 17 days of incubation.
The important thing is that the eggs should be turned an odd number of times so that the side that is up longest will be staggered from day-to-day. Otherwise the egg will be in the same position every night, which is likely to be the longest stretch of time between turns, assuming you are not going to get up in the middle of the night.
Before you put your eggs in the incubator mark them with a pencil so you can tell when they have been properly turned. An excellent method is to put an X on one side of the egg and an 0 on the opposite side. Then you can always tell when the eggs have been turned, because either all ’0′ ‘s or all ‘X”s will be facing up at the same time.
When you turn the eggs, move them to a different part of the tray to offset variations in temperature in the different parts of the incubator. Eggs should only be turned up to day 18, after that they should be left to allow the chick to position itself properly for hatching.
If you are hatching chicken eggs they take twenty-one days to hatch when incubated at optimal temperature. However do allow an extra couple of days before discarding any unhatched eggs as there are always exceptions.
Don’t try to help the chick out
Once you see a pip (hole or crack) in the shell, don’t worry if it takes the chick a while to get out and it appears to be struggling, this is natural. Never try to help by pulling the shell off on your own as a chick can bleed to death as often there are still blood vessels around parts of the membrane that have not yet been cut off. It is normal for a chick to take on average five or seven hours, to emerge from its shell and even up to twenty-four hours is not uncommon.
Power failure or interruptions during egg incubation
Power failure during incubation can be a worry especially if you live in an area that is prone to power supply problems or sudden severe weather conditions. Correct temperature control and related humidity is of course vital to successful chick hatching, but if you do experience a power failure do not immediately scrap the batch of hatching eggs as most times you can save them. Although it is not advisable chick embryos have been known to survive temperatures of below 90°F for up to 20 hours
The important thing is to keep the eggs as warm as possible until the power returns. You can do this by wrapping blankets around the incubator to keep the heat in, ensuring of course that you allow some air through, otherwise you will suffocate the embryos.
If the power is to be out for a while another method that can be used, if you have a small or medium-sized incubator is to cover the incubator with a box, inside the box you can place candles in jars. The candles should produce enough heat to maintain the correct temperature until the power returns. The box can also be wrapped in a blanket for extra warmth. Again ventilation is important so ensure that you leave plenty of air holes. In addition care should be taken to ensure that the jars, with the lit candles are well away from anything inflammable, or the side of the box. Also be vigilant that the candles do not burn too low or in any way produce too much smoke.
Of course the best solution is to have a backup generator or an electrical socket that can be attached to your car battery which the incubator can be plugged into.
Candle the eggs 4 to 6 days after the power has returned to check that development is proceeding. If you do not see any signs of life or the embryo has not developed or of course if an egg has a bad odor you should dispose of it. In general, you should expect a power failure to delay hatching by a couple of days and also reduce your hatch rate.
Advantages and Disadvantages of Using a Broody Hen to Hatch Eggs
There is nothing better than seeing chicks looking out from underneath a mother hen or diving back beneath her for safety and warmth, just as nature intended. However finding a broody hen and successfully hatching eggs may not be as easy as it sounds. Here is a quick look at the advantages and disadvantages of using a broody hen to hatch eggs.
The advantages of the Broody Hen
- The broody hen is usually more successful in hatching eggs than an incubator.
- You don’t have to worry about power-cuts.
- You don’t have to worry about keeping the settings of your incubator right or about turning eggs.
The disadvantages of the Broody Hen
- You don’t always have a broody hen when you need one, or hatching eggs for a broody hen when do.
- You cannot hatch as many chicks under a broody hen as you can with an incubator.
- You need to provide a house and a run for a broody hen for quite a long time during the incubation and rearing process, even if you only hatch one chick.
Incubation with a broody hen has better hatching results and takes a lot of the effort out of the process. But an incubator will give you more flexibility with regard to when and by how much you increase your flock.
