Hens will still lay eggs without having a rooster, but These eggs will never create into chicks. Only any time a rooster is part of your respective flock is there an opportunity the eggs are fertilized.
2. The "Blastodisc" vs. "Blastoderm" Check (Breaking an Egg Open up)

Unfertilized egg: You’ll see a tiny white location called a blastodisc—a little, strong dot that appears just like a speck of flour.
Fertilized egg: The place will surface as a blastoderm—a bigger white circle with a clear “bullseye” pattern, indicating early cell division.

When to candle: Get started all around Working day 5–7 of incubation.
What to search for:
A spider-like Internet of blood vessels or maybe a dark place (the embryo) alerts a fertilized, creating egg.
A clear egg without having visible progress ordinarily indicates it’s unfertilized or not feasible.
