You may have come across beautiful black chicken eggs trending around the internet at some point and this left you with a dream of adding them among your different eggs archive basket.
But, I hate to disappoint you, that is all that they are- an illusion.
Black chicken eggs do not exist unless you transform them with color, which is obtainable.
Having seen a lot of them circulating on social media, there is a reason this rumor got started. Despite the eggs are not black, the chickens are ( they are just as beautiful as those fake black chicken eggs).
