How do farmers control whether a chicken lays an eating egg or a reproductive egg and how can they tell which kind is laid?
In: Biology
As an additional note to what others have said, many farmers have a variety of chicken breeds on their farms. Some breeds of chickens instinctually are more attuned towards nurturing eggs by sitting on them. Other chickens have been bred to just pump out eggs and will not sit on their eggs, thus, even if they are fertilized they won’t grow up to become new chickens.
So in a way, another method of controlling reproductive eggs vs eating eggs is through the choice of chicken breed.
I know this from working at an organic farm, but even there, they had incubators to ensure certain eggs successfully led to new chicks being born.
