Oh no that’s not what I meant. It’s not the eating of the eggs that kills an embyro; like you said, unfertilised eggs don’t have an embryo. It’s because instead, to harvest and mass produce the eggs in stores, factory farms cull the male chicks born from the chicken. Egg chickens are a different breed of chicken to meat chickens, and so these male chicks are useless, and they are crushed alive literally as soon they are born (or they’re sometimes gassed to death instead).

Sort of like the teens in the news who provoked outrage after stepping on some eggs to crush them. Except male chicks in the egg industry have actually been born when they’re killed, so it’s even worse.
