 Marans of America Club also strives to get the  best egg color for the breed. Maintaining  the correct egg color is just as important as the plumage in the Marans.

One cannot have one without the other.

GENETIC ORIGIN

The laying of brown-shelled eggs in the Marans is due to the inescapable presence of hereditary genes that are very complex and, to date, undiscovered (“the genetic linkage” of this characteristic is therefore unknown).

The complexity of the inheritance of extra-russet-red egg colour would result from the presence of several genes and not of only one, of which some genes would be dominant whereas others would be recessive.

Given these conditions, the heredity of dark brown eggshells is automatically reproduced only if the various genes responsible for the brown shells are joined together in the genotype of the subject considered.

We are thus well in the presence of a breed characteristic for which the laws of its genetics still hold many secrets.

We can note in addition that the genes causing “creamy-white” eggs (these even not decoded to date and perhaps quite as complex?) would be rather dominant compared to those causing “brown eggs.”

Moreover, if the report which is made of a greater effectiveness in the transmission of the genes for dark eggs by cocks more than by hens is proved to be a reality with concrete cases in the Marans, then it would be possible to imagine that at least one of the unknown genes causing extra-russet-red eggs would be “sex-linked”, i.e. present in the double state in the cock.

Consequently, in ameliorative crossings for extra-russet-red eggs, when a purebred cock is mated to a non-purebred hen, the cock would visibly transmit his dark-egg genes to all his descendants, while a purebred hen, if mated to a non-purebred cock, would have visible evidence of the dark-egg genes in only with half of her descendants.

This could explain the impression of a greater effectiveness of the cocks to transmit the characteristic of dark eggs in the first generation.

Attention must be paid as this situation is indeed misleading; it describes only one coupling of subjects which one can suppose non-purebred, at least to some extent, for genes related to the characteristic of “brown eggs.” With time, the recessive brown egg genes will reappear.

The Marans egg is without any doubt the darkest hen’s egg. This is a characteristic shared with the Spanish breed Penedesenca, but it is accompanied exclusively in the Marans by a spherical form, a size and a brightness above standard.

How to keep the color.
If one mates a cock that is 100% pure for the dark brown egg genes with a hen quite as pure for these same genes, one will always obtain 100% of pure offspring; but if the transmission is quite as influenced by either the cock or the hen, it is not important whether the genes are known as “sex-linked” or “autosomal.”
What causes the color.?
The color comes from a process of saturation of liquid coloring on the shell, not in the shell. This happens in the last 10 centimeters of the oviduct of the hen. Immediately after the laying this mucus covering dries quickly  and this becomes part of the shell coloring. This is in the breeding of the birds.  Many have tried  different techniques such as  feed and other additives to get only a temporary color but the true consistent egg color comes within the breed itself.

Freshly laid egg can have the color  smeared if it is not allowed to dry before handling. That is why some eggs even pick up straw marks in the egg color if the hen is laying in a nest with hay. This is why called the Marans egg a painted egg. 

The best way to  decide you egg color is to wait until the hen has laid a dozen egg consistently.
 
 Setting your Marans eggs is a little different from other poultry and this we must keep in mind.  This is due to the coating on the eggs.  101.3 degrees and a humidity at 65 %  is what is noted on the MCF  site. But a breeder has to find what works best for them. and their  incubator. Many factors in different breeding techniques can make a big difference.

SYNTHESIS In a survey conducted by Ch Chauvre (63)

SHOULD WASHING EGGS?


I got on different forums and by breeders independent people or 32 responses likely be classified into three groups, others had no opinion marked and therefore I do not hold back here. I'll almost "copy paste" two or three responses because they appear to me very specific and technical. I will cite no source for they come from different backgrounds but the following place, Some will recognize themselves. The purpose of this investigation is to provide as much information on a topic who raises some questions among many. I'm the rapporteur.

1 -- NOT TOO: 8 ratings up 25%

Comments If they are dirty, wipe them humectant but not Incubate - better to wash and maintain the nests - best to clean with paper towel

2 -- AGAINST: 8 ratings up 25%

Comments "In a farm I know they rub slightly steel wool I'm just wipe with a towels - Shell becomes porous and it lets the microbes - I was always told that it was not wash eggs - eggs that have been soiled I make the hull as the water boiling kills microbes - this removes the outer skin.
"I am not in favor of egg washing, except just before the break to put them in the food. Indeed the eggs are surrounded by a membrane invisible because prevent the entry of vermin may infect chicks. That x or y, Specialist Brooding artificially make it a choice that we do products and machines for washing eggs this normal reports of dough and then to the centers of concentration such as poultry for reproduction egg fertilized and gigantism Hatchery Industry is certain that the seeds must be more that many ... ¤ in the chest State ... .... Have Breeding healthy and vaccinated poultry houses that are not defiled with pigs and number of nests sufficient well garnished with shavings or straw .. roll "

3 -- FOR: 16 ratings or 50%

Comments "My first brood one egg has hatched washed And since I wash all the time I wash the brush and I and I check there is not any crack -- I wash them well before eating them - it sells washers designed to facilitate embryonnage. - "In the principle I am not a fan of washing but I arrived to remove the bulk of the egg. In fact I tempering the egg in water in end of incubation to see if the chick is alive, attention to water 39 ° and not long runs if he is dead, if it floats it is living, if moving miracle he is alive and I commend in the incubator. My eggs are all clean before being incubated are brushed to remove defilements or washed in warm water if the brushing is not enough I shall not soon. --
Action by a farmer confirmed recovery a Science: Each egg is cleaned and disinfected. If the nest is clean, there is little or no deposits foreign on the surface of the shell. Otherwise a superficial scratch or washing with hot water is needed the following disinfection soon, the best method is to immerse the egg few seconds in a bactericidal solution, marketed generally by manufacturers incubators. The solution disinfectant must be temperature warmer than the egg (40 to 60 °) so prevent the entry of liquid into the egg, and instead to promote expulsion of microorganisms through the pores of the shell When immersion, he should always keep the big pole up for prevent air pocket of air expands, not off the shell membranes. Once disinfected egg is placed on a grid (disinfected) for drying before placing incubation. It is possible to sterilize eggs fumigation with formaldehyde, but it must done Low temperature (20 °) and not that destroys germs located on the surface of the shell. In addition they are strongly recommended between 2 and 4 day of incubation or just before hatching when chick pierced the pocket air.
Scientific opinion: YES, wash eggs for consumption, concealed to avoid catching salmonellosis! Do not hesitate to rub with a scotch brite the stains of droppings which adhere strongly. (this can happen in any laying nest even own any). For eggs for the reproduction, the first thing is to have a preventive health and drastically change the straw nests often. This does not prevent virus agglutinate ; Virus newcastle is specialized for that when hen is the egg, she filed a substrate colorful or not on the shell, the virus sticks to the substrate before it dries, allowing it to infect the when chick it will pierce the shell. You can bathe the eggs we wants to hatching in a bowl with water to 10% formalin. (half hour). But beware, formalin is effective as from 20 ° c water must therefore, be warm, without more, to avoid mechanical hot / cold. It avoids rubbing the eggs, except obligation to keep the film substrate, useful when incubation. Then, place a container with formalin in incubator - FUNDAMENTAL ERROR should not confuse steam liquid. A liquid will not pass the shell is a filter molecular, but vapor pass (Basic Law the migration of vapors and their passage status liquid. - Brief the egg does not let that oxygen or vapors round the side because water in evaporates from the endosperm pointed end, the phenomenon "pump-down Nothing else can cross the barrier of the shell, not even a virus. The evidence, if you put an egg on your buffet room temperature each day he will lose weight after six months, he weigh more than the weight of the shell + / - 7g - a Egg could never, it stays clean inside during centuries but if there was a crack MICROSCOPIC the ... hens come to see any default, any crack on an egg, if so, they break knowing it will not work and like nothing in nature should be lose ... they eat.
