This is a lot like raising and hatching chickens or Coturnix quail:
– You aren't going to know the outcome 100% until they hatch – You need a male – Females can eject the sperm if they don't like that male
When you crack an egg you can look for a bullseye pattern to see if the egg has been fertilized.
The most reliable way to tell if an egg is fertilized is to candle them after a few days in the incubator. Personally, I wait until day seven to make sure that I can see development for sure.
