Mottled Black Copper Marans?

[Autumn Rosnor]

I have two black marans hens and two roos. One roo has a sideways prong on his single comb, while a hen? has two mottled on her tail and the other roo's toe feathers are mottled.

The question mark is there because she's either a non-pb hen, bms can carry the recessive mottle gene, or she's a roo.
I thought it was that last option for a long time. But she's only a roo if roos will mount other roos.

The second hen I thought at one point had a bib of silver, either lacing or mottling, but she was broody recently and I don't see any now.

So I wonder, has anyone ever had recessive mottling show up in their marans?

I also had a cockerell from a b marans/ameracauna x mottled java/ameracauna that was mottled black. (That b marans my friend's roo)

So I'm wondering---as the mottle gene is recessive, can pb bcms be mottled? Has anyone ever had recessive mottling show up in their marans?

If they can, I may want to buy more stock from my friend and see if I can breed more mottling into them.

[Sorry, I edited this for clarity.]
Will add pics of mottled roo once I have them.

Pictures please.

Pure bred BCMs aren’t mottled because they don’t carry that gene. Can I see a picture?
