Mutant white Black Copper Marans

[newhobbie]

So when I purchased my bcm I was told that they were from a flock that produces mutant white. I think I hatched one. Photos below. Can someone please explain this or point me to a website or article on them? My google searches are pulling up very little and what is out there doesnt explain anything. Any info would be appreciated!

Sometimes black copper Marans to throw Wheaten Marans. that looks like a yellow chick. I would check with some Marans Chicken Club USA and see if you can find somebody there who has white parents .
best,

I had two chicks hatched to my blackcopper marans and they came out light yellow, as they grew it turned out they are wheaten marans.
