Hi,
Just a thought here. It is not necessary to combine two or more different strains for biodiversity when creating a new flock. Especially in poultry and a breed like Marans which has been so thoroughly homogenized already by inter-breeding strains. In fact, the classic texts by legendary poultry breeders advise against it because of the additional genetic variation it brings to the table when one is trying, instead to fix type in a new strain.
Poultry can easily withstand inbreeding because of their wide genetic base and plethora of sex-linked genes. I understand many out there in the wilderness are crying out for random matings , open pedigrees, and loose line-breeding to create their beloved biodiversity. However take a look at what these biodiversity folks are breeding as their end product. There's the rub. They are selecting for land-races and culling only for vitality and ability to work. They do not cull for breed type, other than general characteristics common to that breed. They do not cull for color. Now their philosophies have seeped into the purebred animal breeding world. They do not work here. They are a half-truth in our world. Beguiled by the nice sounding words of vitality, production , ability to work,( and a desire to preserve rare breeds) classic animal breeders try their biodiversity breeding techniques and end up with....squat.
Classic animal breeding is oil and water to biodiversity folk. The two philosophies will never mix and never produce success when tried together in poultry. Because biodiversity folk want general results with biodiversity. Classic animal breeding seeks specific results with biodiversity. In classic animal breeding, we select for particular traits of function, vigor, specific breed type, and color. We selectively cull our breeding stock which maintains biodiversity. As the noted geneticist Prof. Bell states:
"It is the varied opinion of breeders as to what constitutes the ideal representative of the breed, and their selection of breeding stock that maintains breed diversity."

So do not be sucked into the drain of thought which says you need to combine 2 or more strains to found your flock. If you like your lovely hen, go back to that breeder, (or a breeder with a line closely genetically associated with that breeder's line), and get a stunning roo and another hen. Ask if they have adults from trimming their flock which they might sell to you. That way you can redeem the time lost with the ugly birds and stay on track for a nice breeding season next Spring.
