There is a copy in the September issue of one of my FancyFowlUSA Magazine, September issue. I have a copy of it on my Personal Pages, from the French Marans site.
You can get one directly from them, it takes a long time, I've heard.
From the French Marans Website:
1 - White egg : example : Bresse-Gallic or Leghorn, Braeckel for foreign breeds.
2 - Tinted egg : Wrongly called brown in most of the foreign breeds standards as for instance the Rhode-Island. As well, it is the colour of eggs from numerous industrial hybrid stocks, never laid by a pure-bred Marans.
3- Red egg : its a Marans egg but its an unsatisfying selection. The colour is insufficient when its usual in the stock which didnt show any occasional superior specimens.
4- The real extra-red Marans egg
Note : The colour of the egg is not better than the egg n°3, but the pigments quantity is more significant, its stained repartition is uneven, and thats why the extra-red egg is more valuable. A little brightness should always highlight this egg.
Experience : The egg n°4, placed on a natural red earthenware bottom, has to be a bit darker.
Note : the same hen can lay an egg that is slightly darker with an even colour in the beginning of the laying (first 20 eggs).
5 to 9 Extra-russet-red egg (chocolate)
You may notice the spherical, globular shape which is typical to the Marans egg, and the brightness is always an extra property for this egg. Unfortunately, the hens laying eggs 7, 8 and 9 are not often selected for the body standard : light or skimpy subjects, squirrels tails, impure feathers and colours, etc You cant succeed in all matters, though! The selection of the Marans is a very hard work and a long exacting task.
8 and 9 Exceptional eggs or rather accidental : the colour is close to the unalloyed pigment. Once again, you may notice that such eggs are obtained in the beginning of the laying. The fact that the shells pigments tone down in the middle of the laying period is normal. The best shells stabilize around 6 and 7. A good stock can produce an important proportion of eggs 5 and 6. A drastic selection done years after years must maintain constantly that stock.
You can value the quality of a laying hen according to the colour of the eggs in the beginning of the laying after the first 20 eggs and the regularity of this colour during the greater part of the season.
