White or Brown: Eggshell colour is determined by the type of hen that lays it. There is no nutritional difference.
White eggs are laid by white-feathered hens.
These are the most common laying hens in Canada. White eggs are usually less expensive than brown eggs.
Brown-feathered hens usually lay brown eggs.
Producing brown eggs costs more because brown hens are larger than white ones and they eat more feed.
