I was told to boil the eggs with mix water and vinegar to remove the shell easily. But then the brown colored eggs peeled off its color. I think the acid acted upon the outer layer of the shell. My eggs were bought straight from the farm. I don't think my "busy as bee" niece herself had the time to dye the eggs and then sell it with the same price as the white eggs. Would it be a waste of money and time if she does that?
She sells her eggs by the size and not by the color of the eggs.
