I've been puzzled by the uniformly-toned eggs we buy from the

the hens. :-)

To assist in solving this, I'd like to hear from people who raise
their own chooks: after you empty the shell and peel off its
translucent white membraneous liner, is the revealed inside surface
of the shell the same brown tone as the outside, or is it white even
when the shell's outside is brown? -- John Savage

we have our own chooks - but i'm reliably informed by some breeders
around here the shell colour is pretty much dependant on the feed....

just avoid the ones that glow in the dark ;-}
From this website, information as I wrote previously. I do believe that
some feed is now available to colour them differently. So the other
answer is also right in a way..

Why are some eggs brown and some white? It is a matter of genes. Some
breeds of hen such as the Rhode Island Red lay brown eggs, while others,
like the White Leghorn, lay white eggs. Brown or white, there is no
difference in nutritional value or cooking performance.
