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?

Most of the time, assuming the eggs are from chickens being raised properly, there’s no discernible difference in nutrients between the different egg colors. However people like their nice, white eggs so will pay more for those. So the store charges more for what people are going to buy.
