I’m not that keen on eggs either.
The shell colour is due to the type of hen. And, the choice of colour depends on the purchasers.. The British favour brown eggs because they think they are healthier (like brown bread), in France, I believe all the eggs are white because they don’t like brown ones….
Last week I bought brown eggs (free range) in a small local supermarket in France (fairly rural village area) - I doubt they’d bother stock them if they weren’t popular. It’s much easier now to be able to find FR than it was a few years ago.
