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

'changing consumer demands'. The eggs, not 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?

These are the result of cross bred hens. The uniform size is caused
by
their grading process and the colours are probably graded that way
too.
But never fear nothing is wasted and all the egs not conforming get
used
in other ways. But it causes a major waste in resources in labour to
do
this. Supermarkets making the demand as a rule.

Re dyeing eggs, Dont think its necessary, but could be done I
suppose,
but creates another process which I think they would rather avoid.
Its
cheaper to just grade them.

I grew up on a poultry farm and I agree with everything Jonno has
written.
