How to Tell a Fertile vs INfertile Egg (Pictures)

[makmama01]

Thank you Speckledhen! Got my bullseye, now I know my hens are laying fertilized eggs

I am on my way to hatching my first set of chicks and I am so excited. I am eagerly awaiting for my incubator to arrive.

Probably, but not necessarily. How old are they? If prior to about 16-18 weeks old, they may not be fertile yet. My first rooster was 10 months old when he met the girls. It was 5 months before fertile eggs. He'd never had hens before and was very laid back.

they are about 7 months old

Then, you can crack one open and use a spoon to turn the yolk so you can see the blastodisc and then, you'll know.

Can everyone see them... two very different looking blastoderms but both fertile.

Can someone help me out in determining fertility of my eggs? here's the link to the pictures and story behind my fail at incubating my first batch. Any help would be great, thank you.

Thought you'd like to see this since so many have asked how to tell if their eggs are fertilized. The first picture is an INfertile egg.

On this one, you can see the ring, indicating fertility. This is caused by cells in the center of the blastoderm dying off and leaving a cleared out area, making that bullseye appearance. Not all are as clear as this one is, but you get the idea.

**sorry for the graininess of these photos, but they were from years ago and a not so great camera.

How do you get the egg back in the shell once you know its fertile!

I would say no. but if you watch your hens and see them allowing the Cockerels to do there business, probably . I have one Rooster with 25 hens and pullets and he can't kiss them all! He tries but some or the girls are to fast for him.
