Silver deathlayer?

[Nga]

Ok I hatched some death layer eggs, the chicks was born brown and I thought they will change color to white as they get older, they are still very brown at 5-6 weeks old. Are these not silver deathlayers?? Black ones are copper marans. I have them in this small cage while we are waiting for their coop to be built..

They appear to be mixed breeds.
