What does a chicken egg look like when it is fertilized?

All eggs will have a small pale circle in the yolk – this is the blastodisc (genetic material from the hen). If the egg is fertilized, the roosters’ genetic material will be added to the disc making it a blastoderm. The disc will now take on the appearance of a bullseye.

How do birds get their babies back in the nest?

Birds cannot get their babies back in their nests. Most non-birds of prey do not have the required muscular strength to lift up a baby bird into their nest.

What happens to the egg when it is fertilized?

All eggs will have a small pale circle in the yolk – this is the blastodisc (genetic material from the hen).
