The First Generation: Duke of Wellington, Chanel, and shuffling Gold
Having established the aim of reviving the English Golden Cuckoo Marans, the next question is straightforward: where does the project actually begin?
The answer lies not with Golden Cuckoos themselves, but with the birds that still carry the ingredients needed to recreate them.
One of the most important birds in the project is Chanel, a French-standard Blue Copper Marans hen from my very first hatch of Marans. She has become one of the foundation hens of the flock: a large, productive, long-lived bird with excellent Marans type and consistently dark eggs. Alongside Chanel, several carefully selected French Black Copper Marans hens contribute the rich egg colour and gold-based plumage that modern English Silver Cuckoo Marans lack.
One of Chanel’s daughters, Claudie, has inherited much of her quality and has become the darkest egg layer in the current flock. She represents exactly the sort of maternal line that deserves preserving, even while individual faults—such as the high tail inherited from her sire—are carefully selected against.
The foundation sire chosen to complement these hens was Duke of Wellington, my English Silver Cuckoo Marans cock. At first glance, a Dark Cuckoo may seem the more obvious choice. However, one of the key reasons for choosing a Silver Cuckoo lies in the genetics of plumage.
Both Silver Cuckoos and Black Copper Marans are based on the birchen (Eᴿ) allele. Although they look very different, they share the same underlying plumage pattern, with the Silver Cuckoo carrying the dominant sex-linked Silver (S) allele where the Black Copper carries the recessive gold (s⁺) allele. Crossing these two varieties therefore allows the project to exchange silver for gold while keeping the same underlying birchen pattern intact.
A traditional English Dark Cuckoo, by contrast, is typically based on extended black (E) rather than birchen. This pattern is dominant to birchen and hides and gold and silver that would otherwise show. That extra layer of complexity would make it considerably harder to recognise and select the birds needed to rebuild the English Golden Cuckoo.
The principal mating therefore became:
Duke of Wellington × Chanel
English Silver Cuckoo × French Blue Copper Marans
Additional matings paired Duke of Wellington with selected French Black Copper Marans hens.
Genetically, these matings are surprisingly elegant. Duke of Wellington contributes the dominant Silver (S) allele, while the copper hens contribute gold (s⁺). The resulting F1 cockerels are therefore expected to be S/s⁺: silver in appearance, yet carrying gold hidden beneath the surface. They also inherit the birchen background from both parents, meaning that the framework needed for the future Golden Cuckoo is already present in the very first generation.
This hidden inheritance is one of the reasons the F1 generation can appear deceptive. Many of these young cockerels simply resemble Silver Cuckoos. Genetically, however, they are carrying half of the material required to recreate a Golden Cuckoo in the following generation.
The hatch produced eleven surviving chicks, reared successfully beneath Silkie broodies. Among them were two blue cuckoo cockerels from Chanel, several silver cuckoo offspring from the Black Copper hens, and lavender silver birds from a separate lavender breeding project.
As the youngsters developed, each began to reveal different strengths. Some possessed remarkably clean legs, an essential feature of the English standard. Others developed heavier shank feathering inherited from their French ancestry. Some carried exceptionally clear barring, others broader bodies, better tail carriage, or superior overall type.
One cockerel, Blue Band, emerged with outstanding body shape and remarkably crisp barring, although he also inherited the heaviest leg feathering. Another, Brown Band, initially appeared promising for his size but later developed a noticeably longer, higher tail and gradually lost his advantage in body mass (this boy will therefore not be used for breeding). Chanel’s two sons also diverged, but neither disappointed. Purple Band retained excellent mass and type, plus a lower tail, while his darker blue brother, Nelson, remained clean-legged, making him particularly valuable as a potential route back towards the clean-legged English standard.
Perhaps the most encouraging outcome has been the performance of Claudie’s daughters. As hens only inherit gold/silver and barring/not barred alleles from their sire, all pullets are silver cuckoos like Wellington. Assuming the chick identifications remain correct, they combine one of the strongest dark egg lines in the flock with excellent body shape, giving future generations the opportunity to preserve these maternal qualities while correcting inherited faults through carefully selected cockerels. While it may seem counterintuitive to produce pullets that are the same variety as Wellington, they do not have any impact on the barring or gold status of their female offspring. This means they can be used solely for type and egg selection, while the future sire handles the sex-linked genes desired for F2 pullets.
This is the stage where breed restoration stops being theoretical genetics and becomes selective breeding. No single bird possesses every characteristic required. Instead, each contributes one or two pieces of the puzzle.
The task now is to assemble those pieces patiently.
The first generation was never expected to produce finished English Golden Cuckoo Marans.
Its purpose was something far more important.
It produced the genetic foundation from which they can eventually emerge.
Reviving a lost variety
Among British Marans breeders, the Dark Cuckoo has long become the familiar face of the breed. The clean-legged English Dark Cuckoo remains one of the classic British utility fowls: practical, handsome and capable of laying the dark eggs for which Marans are famous.
Yet hidden in the British standard is another variety that has almost disappeared from our poultry yards: the Golden Cuckoo.
The British Poultry Standards still describe the Golden Cuckoo Marans in considerable detail, with rich golden colours in many parts that are black and white in Silver and Dark Cuckoos. Unlike the French Marans, the English standard also calls for clean (featherless) legs. The variety exists on paper, but genuine examples are now extremely difficult to find in Britain — if not extinct.
Many modern Marans descend from French standard Marans, with black copper and blue copper varieties becoming increasingly popular. These birds are often excellent in their own right, but they are not regarded as breed-standard under the Marans Club of Great Britain.
My own interest lies not in producing another attractive hybrid, but in attempting to recover the English Golden Cuckoo Marans: a show-quality, dual-purpose bird combining dark eggs, good utility qualities and the warm golden barring described by earlier British breeders.
The project begins with the birds that survived. English Silver Cuckoo Marans remain established (though commonly labelled as simply ‘cuckoo Marans,’ meaning knowledge and test matings are needed to distinguish them from the more common dark cuckoos), while dark egg strains of Black Copper Marans provide the egg colour that made the breed famous, as well as the gold genes that makes this variety stand out. By combining these lines and selecting carefully, the aim is to recover not only the colour, but also the qualities that make Marans unique, those that were lost by careless or intensive breeding.
The first generation has already produced considerable variation. Some birds possess stronger barring, some greater body width, some cleaner legs, some heavier shank feathering, and others deeper egg colour. This is not a sign that the project has failed. Quite the opposite. It demonstrates that many of the ingredients required to recreate the old variety still survive within modern stock.
Several principles guide the breeding programme:
dark eggs remain essential;
utility and body shape take priority over exhibition colour;
clean legs are preferred in accordance with the English standard;
tail carriage and sound structure are selected carefully;
the golden barring of the old British standard remains the long-term objective.
Breed conservation often sounds grand, but it usually begins in a rather humble way: a handful of eggs, several uncertain young birds, and a breeder attempting to recognise the future among them.
While the English Golden Cuckoo Marans may well have disappeared visibly in the UK, the component genes are scattered among surviving lines: hidden silver cuckoo and copper Marans. The challenge now is to gather those pieces together again.
Future posts will follow the progress of the flock, the decisions behind each mating, and the successes and failures involved in reviving one of Britain’s forgotten Marans varieties.
