What would a BCM x barred rock look like?

[Chicken boy 1156]

I’m curious what this chicken breed would be if you combined these 2 breeds. It just came to my head so sry if there’s already a post about it

Such a cross wouldn't result in a breed, but a mix in the offspring. And what would result from that mix would depend on which parent was of which breed.

A Black Copper Marans rooster crossed to a Barred Rock hen would make sexlinked chicks. All males black with a white head spot at hatch, females black with no head spot. The males would feather in barred like their mother and females would be mostly black with no barring. Either sex could have varying amounts of gold or reddish color leakage.

A Barred Rock male crossed to a Black Copper Marans hen would make all barred offspring, males and females, with varying amounts of color leakage.

Of note, in either case, the males would not be pure for the barring gene and thus would look darker than a pure Barred Rock male, more similar to the darker barring of a Barred Rock female.
