How do you pick fertile eggs for hatching?

Don’t select eggs from hot nests or those in the sun. Choose eggs that are 1.4 times longer than they are wide.

Which eggs are used for hatching?

It is always preferable to choose eggs weighing about 58 g each. Eggs that are uniform in size and shape are preferable. The eggshell should be equal in thickness, texture, and color so that warmth can spread uniformly throughout incubation.

What’s the difference between fertile and fertilized eggs?

Identifying a Fertilized Egg From the Inside Examine the egg for the germinal disc, a white spot floating above the surface of the yolk. The germinal disk of a sterile egg contains only the hen’s cells and is fully white in color. In a fertilized egg, the germinal disk contains the merged female and male cells.

Will all fertile eggs hatch?

No, a terrible hatch doesn’t mean that most or even any of your eggs were infertile! They may all have been fertile. Remember, just because an egg doesn’t hatch (or even if it doesn’t develop), that doesn’t mean it wasn’t fertile.

How can you tell if eggs are fertile?

If you crack it open, a fertile egg can be identified by a small white circle on the yolk, that has a ‘bullseye’ like shape – i.e. one small white circle, with another white ring on the outside of it. This is created by a cluster of cells that, if incubated, will hopefully develop into a baby chick.

How long will fertile eggs keep?

Under ideal conditions you can keep fertile eggs for as much as 24 days and they will still hatch. Hatch-ability drops off considerable after 14 days so you should aim to set you stored fertile eggs in and incubator or under a broody hen within two weeks of the being laid.

How can you tell if egg is fertilized?

When you crack open the egg, if it’s fertile, you’ll notice a small white spot on the top of the yolk about 4mm in width. This is called the germinal disc. This is what tells you if the egg has been fertilised. This disc is formed with a single cell from the female and a single sperm from the male.
