The only way to look for fertilization right before incubation is by cracking the egg open up and inspecting the germinal disc (a small white spot on the yolk).
Unfertilized egg: You’ll see a very small white place named a blastodisc—a small, solid dot that appears just like a speck of flour.

An Lively, dominant rooster
Mating habits from the flock
Fertility confirmed in sample eggs
…all propose very good odds that eggs through the very same hens are fertilized.
