Why are some chicken eggs white and some eggs ‘brown’ or ‘speckled’? Is it related to why supermarkets sell mainly packages of eggs of the same shape and colour per package and why those packages are all differently priced?

Question

When I say differently priced I mean by egg ‘quality’ (like free range vs caged, although I’m not sure the exact mechanics of how that correlates to egg quality; I can imagine it impacting flavour though – happy chicken, yummy eggs?) not by the number of eggs sold per package, although that may have something to do with pricing, who knows?

There’s no difference in the egg it’s just genetics it’s like asking why someone has black or white skin or freckles. The only reason white eggs are more common and more expensive is because people associate whiteness with cleanliness.
