Brown Eggs v White Eggs?

I can remember as a child the best 6 eggs competition held at Delabole Fete, and looking in wonder at all the colours and speckles. Everyone of them produced by happy totally free range organic hens. In fact you might find yourself wandering amongst them on various walks etc.

I thought that different varieties of chickens lay differing coloured eggs. Have I had this wrong all of my life?

You are quite right, clg. But the thickness of the shell and the depth of the yolk colour are down to the feed!

I thought it was just me in thinking white shells are more fragile. I had two break on the way home recently, but never brown ones. I get brown eggs now if I can.

That is not exactly what Sainsbury's said. corporate.sainsburys.co.uk/sustainability/explore-by-a-z/agriculture-aquaculture-and-horticulture/sourcing-sustainable-eggs/Here is a link]] to the article.
To me, eggs is eggs. It doesn't matter what colour they are. I haven't found that white eggs are more fragile. The colour of the shell is determined by the breed of hen.
