How to transport fertile chicken eggs to ensure the best possible hatch rate.

So you've ordered eggs by post and you're not sure what to do when they arrive? Or you want to take eggs on a plane but not sure if you can?

How to transport hatching eggs. Pin for later.

It's critically important that the eggs you put into the incubator are as healthy as they can be.

They should come from a healthy flock, be stored at optimum temperatures, be transported as smoothly as possible and left for a number of hours before being set in the incubator.

It's not always possible to collect eggs from a supplier locally - you may need to have them sent by post.

How should they be treated when they arrive?

Or perhaps you want to start a small business supplying other people, in which case you'll inevitably need to send some of your own eggs by post. 

In that case, you'll need to know exactly what the best conditions are to transport hatching eggs from one place to another - within or even outside your own country.

And how long can eggs last between collection and  incubation, anyway? 

In this article I answer six commonly asked questions about transporting hatching eggs, the problems you may face if you buy some to be sent through the post and the potential solutions to those issues.

First, let's look at optimum storage for fertile eggs.


How long can you keep eggs before putting them in an incubator?

Obviously, the fresher the eggs, the more chance of a successful hatch. The longer you keep them, the more their fertility declines.

But eggs can still be viable up to three weeks after they've been laid, provided they're kept in the right conditions. Here's how:

  1. Use the cleanest eggs possible. Dirty eggs have a greater chance of transmitting bacteria once they're incubated.
  2. Store the right way up - the pointed end should face downwards.
  3. Keep the eggs dry, and at an optimum temperature: between 5ºC and 10ºC (40ºF to 50ºF) is ideal.
  4. Turn at least twice each day, more often if possible.

You've received some hatching eggs by post.  What should you do to make sure they're in the best condition?

  • If you know your eggs are at a sorting office, arrange to collect them yourself. Having them bounced around in a delivery van with lots of other packages will not help them survive.
  • Once you get them home, unpack them immediately, being careful how you handle them.
  • Check for any cracked eggs and discard them straight away. Tiny, hairline cracks aren't always visible to the naked eye; the most effective way to look at the shell is using a good candler

  • Most suppliers won't take responsibility for damaged eggs sent by mail, because they (generally rightly) say the damage occurs in the rough handling they often receive in transit. But it's worth informing them anyway, particularly if the eggs don't seem to have been very well packed.
  • Supplied hatching eggs should be clean. If they look dirty when you unwrap them, clean the worst off either with a light sandpaper, or by rinsing gently under cool running water.
  • Now place your eggs into a container with the pointy end downwards and leave, undisturbed, to rest at room temperature for 24 hours. This is a really important step: it allows the air cell to settle back into position after the jolts of transport. 
  • Turn on your incubator and allow it to come to the correct temperature while your eggs are resting. Once the eggs have rested for 24 hours and the incubator's temperature is consistent, you're ready to begin incubating!

What problems may there be with eggs which have been sent by post?

  • Apart from cracked eggs, the major problem with eggs sent in the mail is the disturbance of the air cell. The jolting in transit causes the air cell to detach from the shell.

  • That can lead to an unsuccessful hatch. the air cell is critical for the chick to hatch into - it's where she will take her very first breath. If the air cell doesn't develop, the chick won't be viable.
  • When candling the eggs before incubation, look for a saddle shape, or what looks like an air bubble floating on one side of the egg.
  • How to deal with a detached air cell? Rest your eggs at room temperature, pointy side down, for 24 hours before incubation. In some cases, the air cell may re-attach.
  • There's some evidence that incubating eggs with detached air cells pointy end down results in more success than incubating horizontally. Incubators like the Brinsea Octagon 20 are ideal for this.
  • Some people also stop turning detached air cell eggs at Day 16 rather than 18 to give the fragile air cell more chance to settle before hatch. Does it work? Well, turning at that point is not as critical as in the first days of incubation, so it's worth a try.

Need to send hatching eggs by post? Here's how.

  • Always test for average fertility levels in the flock by incubating a collection of eggs before selling any. Calculate the percentage of those which, when candled at Day 5, have started to develop.
  • Make sure when advertising you are clear about your average fertility rate, and be clear in stating that no-one can guarantee that every egg collected will be fertile.
  • Collect the eggs as quickly after lay as possible, and ship them as soon as you have all you need for an order. There should be no more than 3 days between lay and shipping. 
  • Keep them in a cool, dry place whilst waiting to ship. The ideal temperature is between 5ºC and 10ºC (40ºF to 50ºF). Any warmer and there's a danger the embryos will start to develop, but die before they even reach the incubation stage.
  • The eggs should be clean. Candle them to make sure they have no hairline cracks and are not too porous. 
  • Ship using styrofoam egg cartons. If the eggs are smaller than the cartons allow, pad them with kitchen paper or tissue to stop them moving around. 
  • Pack the carton(s) inside a robust cardboard box with plenty of bubble wrap or other protection. Mark the box "Fragile: Live Hatching Eggs".
  • Obtain proof of postage in case the eggs don't arrive. Let your customer know as soon as they're shipped, so that s/he can make arrangements to collect from the postal depot if possible.

Can hatching eggs be carried by car across State or country borders?

  • Yes. I frequently transport hatching eggs from the UK to my home in Italy. Unable to get the breeds I want in Italy and unable to bring either young chicks or full-grown chickens over, I needed to find a way to grow my flock with the breeds I wanted.
  • Transporting by car within your own country, or across country borders within Europe, is no problem. As long as the eggs are well wrapped, snugly positioned in the car so that they avoid unnecessary bumps and kept at cool temperatures, you won't have a problem. 
  • It's perfectly legal to take hatching eggs into and out of the UK and across mainland Europe. The only time when it becomes problematic to move them from one European Union country to another is if there is an uncontrolled outbreak of avian flu.
  • Checking with the DEFRA website (here's a link) will confirm whether that's a current issue when you're travelling.

Is it legal to transport hatching eggs on a plane?

For detailed information about transporting eggs by plane, see this page.

  • The short answer to this is: ask. Regulations can change quickly, so always check a few days before your flight.
  • I have carried eggs on planes from the UK to Italy without any difficulty. Even though there are stringent regulations about carrying liquids in hand luggage, I was assured that eggs count as solids and are not an issue. And sure enough, I had no problems going through airport security.
  • The one drawback is that they do have to be passed through the security scanners. However, this has never affected the hatchability of any eggs I have carried by plane.
  • To be safe, before you travel always call the airport from which you're departing and the airline you're flying with, to check the current situation. 
  • The same caveat applies as to transporting eggs across any boundaries by car: in the event of an outbreak of avian flu, it will not be acceptable to transport fertile hatching eggs. 
  • Make sure the box you use for carrying your eggs has a lid that locks tightly to the box. I've found this 18-egg carrier from Amazon to be particularly durable.
