Hatching chicken eggs has never been easier with the help of today’s incubators. With them, your whole incubating job is much easier due to the efficiency of this machine. But despite that, you’ll still have a lot of jobs to do before you use egg incubator. And one of the most important things is choosing fertile eggs since it’ll be pointless to incubate an infertile one. So in this article, I’m gonna give you the ultimate guide on how to tell whether your eggs are fertile or not.
Cracking the egg shell
Normally this won’t be the method that everyone love to do, most of them would want their eggs to stay intact. But if you are a teacher and you want to show the clearest and most detailed images of a fertile egg for your student then this is just perfect. Since your purpose is to see what’s inside the eggs and doesn’t care if you have to break it or not, the simplest method is cracking the egg shell. Carefully observe the egg yolk, you’ll see a small white dot. If the dot has a bull-eye lookalike then the rooster has hit the right spot, your eggs are fertile. But in the other case when the white dot looks more like a small period then your eggs is infertile. It’s just simple as that.
Without cracking the egg shell
This is what most people would love to know, especially when you’re a poultry farmer and you want to incubate your eggs. There is no point of cracking the fertile to see if it’s qualified for incubating or not. One of the most popular and accurate methods, in this case, is candling the eggs. Now, this method has a lot of different variants, you can literally candling using a candle, or you could use a flashlight instead. You could also use the candling machine for the job. The original method is often used by poultry farmers in the old days. It’s quite accurate but it’ll cost you a lot of time and effort. It can be performed at home or in small farms but could be industrialized. Using candling machine is very effective but it’ll cost you some extra money purchasing the machine. And since our purpose in this post is to find the easiest and most convenient method, I’ll only talk about the original candling method. Here is how you should do it.
Prepare a bright flashlight, use a paperboard and roll it into a pipe shape that your flashlight could fit into. You could use a plastic pipe or anything that has the same size and shape as a replacement. Turn on the light, make sure it’s bright enough to shine through the egg but not too bright to avoid damaging the egg yolk. Neatly place the eggs one at a time on the pipe to let the light shine the inside of the egg. You’ll see a small dot inside the yolk, what’s left to do is the same as when cracking the egg shell. After choosing the fertile eggs, you could start incubating. But remember to check your eggs again after 3-4 days to see whether the embryo is developing or not. Good luck.
