How soon can you see growth?

[MakNat]

Today at 3:30 will be 72 hours in. I still can't tell if they are even fertile. Is it too soon... I know I'm jumping the gun.. I'm really nervous. They are Leghorns and I am REALLY wanting them!!!!

I candled mine to day. They have been in for 76 hours. I used my daughters wind up light. When I carefully roll the eggs above the light I could see a dark blob slowly move. On 3 others I couldnt tell. Its easyer to tell on the 7 th day.
But look closley its amazing
