Black Copper Marans on average will have the darkest eggs of the breed. Egg photos are pretty meaningless unless the photo is taken with the Marans egg color chart, which is color-matched at each printing. No matter what the lighting, exposure, etc. if you have the egg chart you can see photos like this and know what you are looking at. Ask for photos taken with the egg chart. If they don't have a Marans egg chart, they probably are not serious about breeding these birds. Examples:Hi, I am looking to start a flock of marans from hatching eggs. I am interested in the darkest eggs. I don't show birds but I would like to keep a pure bred flock. I have been looking at FBCM on E-bay auctions but since I am new to this I am overwhelmed. Many of the pics of eggs on Ebay don't look any darker than the eggs I am getting from my Red Stars and Amberlink hens at the beginning for their laying cycle. I know the lighting of pics is very subjective and the people claiming to have the darkest eggs on ebay may be just showing a darker less exposed picture. Any suggestions for breeders with dark layers. Should I buy eggs from more than one breeder to enhance my gene pool from the start? I am a newbie so please educate me. I looking at FBCM since that gets the most "wanted to buy" hits on my local craigslist so I'm guessing that's the most sought after?
APA standard requires all Marans varieties to have correctly feathered shanks and outer toes, so saying French BCM is redundant at the least and untrue at the worst. Unless someone has personally imported French BCM stock, and some have. You will have better luck with egg color if you stick to one line and breed within that line, as often you will lose egg color when outcrossing to other lines for a few generations. Hints to not look like a newbie: Marans is always capitalized and always plural as it is a place name in France. FBCM to me screams newbie for the reason cited above. There are great Marans groups on Facebook and you can learn a LOT by hanging out there. Marans Fanciers and Marans Central are two good ones. Ask how far removed from "XYZ" breeder a person's breeder flock is if they are advertising "XYZ" line. You will see a lot of ads for Davis or Jean lines for instance but unless the birds they are using came DIRECTLY from a certain line, it is also fairly meaningless. Once birds leave a breeder's hands and the mating decisions are being made by someone else, they are no longer that line. Ask to see photos of the breeder flock. Good luck!
