French Copper Marans Rooster X Cuckoo Marans Hens

[BeccaRecca13]

Been searching around to see what info might be out there about French Black Copper Maran X French Cuckoo Maran crosses.

I got what I thought were BCM chicks as part of a rare assortment from Hoovers, which have both breeds. They developed the telltale white outer wing feathers very early, but the remainder of their plumage was an iridescent black. Around week six they started developing the copper collars.
Entering week 8 - they are all developing some whitish dappling on the lower breast and some white feathers mixed in with their black feathered legs/feet. Pics of young cuckoo pullets have the pattern already, but my girls were solid black besides 2 wing feathers. Are they possibly crosses?View attachment 2172466

Did you ever figure out what this was? And how you got them? I received the “assorted marans” and I do believe there might be mixes involved as I have 2 that have a barred look on their chest at 8 weeks, but have the copper around the necks, and feathered legs. They are definitely pullets as there is no sign of combs really, yet.. I wish I took a picture tonight, but I’ll get one tomorrow.

I have a French Black Copper Marans Rooster that has the typical feather footing that the French variety does. I have acquired some "production" or clean legged Cuckoo Marans hens. If I were to mate them, would I: 1) End up with the barred coloring since my understanding is that a barred hen's color will be dominate; and 2) Would the feathering of the rooster carry through to the chicks? It is my understanding from other parts of this site that the French prefer feather legged, and the British prefer clean legged. From a personal standpoint I don't care one way or the other. Both are fine to me. As time allows, I plan on having coops with their own breed per coop/run. I have Rhode Island red chicks coming on, I have Speckled Sussex coming on, and I have a pen with Barred Rock and the Cuckoo Marans mixed together (until I get a separate house/run built and get them separated).

So in case you missed it, the point of the post is to figure out what will happen if a French Black Copper Marans rooster is crossed with Cuckoo Marans hens that are clean legged.

How did this project turn out? I'm Interested in doing the same thing.
