Vegans don’t eat eggs under any circumstance because they belive animals are not humans to use.
Well first of all that’s not what all vegans believe. Many are vegan because of the cruelty. If all animals were treated humanely (but still killed and eaten) there would be far fewer vegans in the world.
Secondly, why would you not use the eggs? If they’re not fertilized then they’d just go to waste anyway.
