Wow; I just read through the whole thread and found all this very interesting. I will be waiting to see what she says regarding the quality of the eggs she sent.
I got started with Marans (Fitch, Ripley, and Braden Cuckoo lines, and Black/Birchin/and Black Copper) sometime around the year 2000 so quality certainly wasn't what it is now, but I can say none of my hens eggs ever lightened that dramatically. Those pictures are like comparing my Penedesenca or Welsummer (pullet) eggs to my Barnevelders (who bless their gorgeous little hearts just didn't get the memo that they are a dark egg laying breed).
And as long as I shipped eggs never sent out an egg that was cracked or shipped. I didn't even like sending dirty eggs.
