Why yellow feathered chicks?

[natyvidal]

No. They hatch yellow and then get their wheaten coloring when they feather out

Got it. In this case their eggs should be dark chocolates! . Right?

A pullet that is half marans, half EE will lay dark green eggs if the father carries the blue egg gene. They are what is bred together to create an olive egger.

If your cuckoo marans hens had chicks with these roos, the light colored ones would have probably been fathered by the lighter of the two.
If your marans mated with a cuckoo marans roo and the wheaten gene is from only marans, they should lay dark eggs.

The father of those chicks is the one with dominant white

which is this one

Dominant white + Extended Black chick down(from Cuckoo Maran Dame) = White chicks with some black dots as seen on the pic

As far as Egg Color goes...

EEs vs Chocolate = At the very least 50% Olive Egger and 50% Brown/Dark Brown but not Chocolate because EEs lay either Blue/Mint Green or Pinkish Colored Eggs

So basically only my three black chicks, out of the 9 brown eggs I was hatching, will provide the chocolate brown eggs, and the yellow chicks will lay blue eggs?

No. They will lay whatever their dad passed them, mixed with brown. So either shades of brown or green

Pictures of parents would be helpful. :] unless your roos are purebred cuckoo maran, the chicks are mix. How long did you have these hens before you set eggs?

I have coocko marans and green Eggers that are black feathered. I think this hen is the mama.

No as both of those roosters are Easter Eggers. I was just mentioning who the dad of the yellow chicks were. None of those roosters are Dark Egg breeds. They are EEs so their eggs range from Blue/Mint Green to Pink/Cream color

Bummer!!!

Bummer!!!

You should be able to get at least 50% Olive Eggers and 50% Dark Brown eggers, so more options for your clients.
