That time of year is almost upon us again – hatching season!
Many of us get the hatching bug and long to hatch out some of our chicks – after all. They are very fuzzy, cute, and endearing. In our guide below, we cover everything you need to know about hatching eggs; from setting up the incubator to what to do on hatching day, we have it all covered.
Choosing Between an Incubator and a Broody Hen
This is your first decision to make. If you have a hen that loves to go broody every year and will sit on the eggs for the required number of days (21 for chicks), she is the best show in town.
A broody hen will sit on those eggs and keep them warm, even plucking her breast feathers so that the eggs can touch her skin.
She will turn those eggs around 50 times every day; she will also talk to the chicks through the shell so that her chicks imprint on her voice and will know who Mama is when they hatch.
Anyone who has seen a broody hen in action knows she will defend her nest with a mothers’ devotion – mind your fingers!
She is also much cheaper and more accessible than an incubator to operate.
Possibly the only downside to having a hen hatch your chicks for you is that they aren’t quite as friendly to you as they would be coming from an incubator – after all, you aren’t Mama.
If you choose to use an incubator rather than a hen, it has some advantages and requires your attention daily (at least) for 21 days and beyond.
It should maintain a constant temperature between 99-102°F (99.5°F is considered optimal) and 50-60% humidity.
So you have to check the temperature and water daily. If your area is prone to power outages, then have a plan B in mind – a couple of hours shouldn’t be too bad, but any longer could be disastrous.
When the chicks hatch, the first thing they see is you – that makes you Mama. These chicks will be friendlier than hen-raised chicks.
They will rely on you to water, feed, and protect them until they are old enough to be on their own.
Where To Find Fertilized Eggs?
Your next decision is where to get your fertilized eggs from. If your flock has a rooster, you need to look no further.
If he is performing his duties, your hens should be laying fertilized eggs.
You don’t have a rooster, what’s next? Do you have a friend that would give or sell you some fertilized eggs?
If so – go and fetch them yourself and bring them home as gently as possible. Eggs do not travel well.
Your third choice is to buy from a breeder or hatchery that sells the eggs you want. Please bear in mind – eggs do not travel well – yes, I’m repeating myself, but this is important to realize.
If you are hatching a rare breed and have paid a lot of money for the eggs, it’s very disappointing to have few if any hatches, and it’s not always fair to blame the breeder.
For example, you buy your eggs from California, and you live in New York. Those eggs have to get from the farm to the Post Office, sorted (not gently either) into the appropriate bin.
They are then taken to the airport and flown to your nearest airport.
They are picked up by the mail carrier and taken to the nearest post office, where you will collect them at the airport.
I don’t know about you, but after a long plane ride, I always feel a bit scrambled – so do your eggs.
You will need to let them sit for at least 12 hours in a cool place with the pointed end downwards. Candle them if you like to see if the yolk is still intact.
On a personal note, I have never had success with shipped hatching eggs.
Since these eggs are from a different environment, it is worth sanitizing the eggs, so they don’t bring any ‘nasties’ with them. You can use a sanitizing solution and water to do this.

Setting Up an Incubator
Choosing an incubator can be daunting. There are many different types out there, and cost can range from just under $100.00 to several hundred, depending on what you want.
If you are hatching out ‘barnyard mixes’ and will be diligent about temperature and humidity, one of the cheaper circulated air (forced air) incubators may do you very well.
Some of my best hatches have been with these cheaper models!
If you are hatching more expensive or rare breeds slightly, a step up to something like a Brinsea may be better for you.
Remember, you don’t need lots of bells and whistles on the incubator. You want something that will do the job well and that you can easily use and understand.
How To Set It Up for Hatching Eggs
There is a shortlist of requirements for your incubator, so here is your checklist:
- Incubator (with turning rack)
- Candling device
- Paper towels
The first thing to do is plug everything in and make sure the incubator and turning tray are working. Leave it on for several hours to make sure it comes up to temperature and humidity.
While you are waiting, make sure you read and understand all the instructions that come with the equipment.
Although your incubator may have a thermometer and hygrometer already built-in, it’s wise to double-check with another thermometer/hygrometer. You can buy cheap digital ones online for under $10.00.
You will use the water to fill the water chamber as directed by the instructions – paper towels are for the inevitable mess.
Go to book – Hatching and Brooding your Chicks by Gail Damerow. This book will prove invaluable to you. It gives tips and tricks, sensible advice, clear, concise information, and a section that tells you ‘what went wrong.’ I would not be without it.
How To Incubate Hatching Eggs
So, you have your incubator running, temperature and humidity are set, water trough filled – now to place your eggs! A turning tray makes it easy to put your eggs, but how do you position them?
The most consistent train of thought is that you place your eggs with the pointed end angled down. The egg should not be upright but lying slightly to the side – as it would be in a natural bird’s nest.
Before placing your eggs, they should all have been checked over for hairline cracks and any shell deformities. You can candle the egg to do this.
Eggs that are difficult to tell top from bottom or long and narrow should not be used as they are less likely to hatch.
Your eggs are placed, now close the lid and begin your countdown!
You will need to check the temperature and humidity in about an hour to ensure that everything has stabilized; adjust your settings accordingly and recheck if necessary.
You should do daily visual checks to ensure the water level is ok, and the temperature and humidity are correct. You may have to adjust the air vents on your incubator to maintain proper levels.
Caution: do not keep opening and closing the incubator. This causes temperature fluctuations which will affect your hatch rates…be patient!

What To Do On Hatching Day
Day 18 is known as ‘lockdown’ day. This is the day when you make sure the egg turner is turned off and set the eggs on the level surface tray of the incubator.
Once you have checked that the water level is sufficient and ventilation is at the right level, put the lid on and leave it alone!
Please do not open the lid. Move the incubator or jostle it around. This is a critical period. The chick is getting into position, ready to ‘pip’ the shell and emerge, so it needs to be left quietly to align itself.
FAQs about Hatching Eggs
How Long Does it Take For an Egg to Hatch?
It will vary by species – chickens are 21 days; ducks are 28 days; turkeys about 28 days; guineas 28 days and geese 30 days.
Do All The Eggs Hatch At Once?
No, but they are usually all done with 24-48 hours of the first pipping. Some hatches can last up to 4 or 5 days, though.
An Egg Has Exploded, What Do I Do?
The egg exploded because it had bacteria in it. The best you can do is clean out the incubator thoroughly (keep the eggs warm), and if eggs are contaminated, clean them off as best you can without removing the ‘bloom.’
What Temperature Should The Incubator Be Set To?
With chicken eggs, you should set your incubator to 99.5°F.
What Is the Warm Water Trick for Hatching Eggs?
There is this so called trick where you put eggs that haven’t hatched in warm water. The warm water trick for hatching eggs is a method to also check to see if an overdue egg is ready to hatch.
All you need is a pot of warm water or sink so the egg can float in. Make sure the water is at 100 degrees or 37.7 degrees Celsius.
Place the egg in the bowl or sink. Be sure to be extra careful so you don’t disturb the chick that is supposedly in the egg.
If the egg floats that means that there is a chick inside.
It floats because as the chick has developed an air pocket has formed inside the egg.
If the egg sinks then the chick did not develop properly and you can toss this egg out.
How Long Does It Take to Hatch a Chicken Egg Without an Incubator?
Eggs hatched by the hen can take up to 25 days. The sweet spot for an egg to hatch is the same for the incubator, 20 to 21 days.
The chicks can pip as early as 18 days old.
Hatching Eggs: Summary
This has been a whistle-stop tour of hatching. We have hit the highlights, but there is much else to learn about hatching your chicks.
I recommend reading as much as possible about it before you try it. It will make you more confident about knowing what to do and how to do it.
You will unlikely get a 100% hatch rate – even the professionals don’t. There are many reasons for that, so don’t beat yourself up.
Reading about failures to hatch and the reasons behind it will help you to understand that so much goes into hatching an egg that whatever you did is not likely to be the cause.
Good luck with your hatching adventures, and send up some pictures of your chicks too!
