White egg laying Roo over Multiple Egg colors?

[KitchenFamilyFarm]

What will I get when I cross these? I can’t seem to find info online about that happens with White egger males when bred.

White Egg laying Roo(California White) over: White Egg (California White) = ?
Pink Egg (Silkie) = ?
Green Egg(Starlight Green Egger)= ?
Brown egg(golden comet) = ?


Also what about non pure bred blue eggers such as the Prairie Bluebell?

Blue Egg laying Roo(Prairie Bluebell) over: White Egg (California White) = ?
Pink Egg (Silkie) = ?
Green Egg(Starlight Green Egger)= ?
Brown egg(golden comet) = ?

This whole breeding for egg color thing is confusing.

I’ve attached photos of all the breeds I’m referring to, along with a photo of one of their typical eggs.

White Egg laying Roo(California White) over: White Egg (California White) = ?

White eggs

Pink Egg (Silkie) = ?

White or cream colored eggs.

Green Egg(Starlight Green Egger)= ?

Chance of several egg colors: white, cream, blue, green.

Brown egg(golden comet) = ?

Probably cream colored eggs.

Blue Egg laying Roo(Prairie Bluebell) over: White Egg (California White) = ?

Blue eggs, chance of 50% daughters laying white eggs.

Pink Egg (Silkie) = ?

Blue eggs, chance of 50% daughters laying cream eggs (or light brown or pink: I don't distinguish those colors from each other).

Green Egg(Starlight Green Egger)= ?

Blue or green eggs, chance of 25% daughters laying white or cream or brown eggs.

Brown egg(golden comet) = ?

Green eggs, chance of 50% daughters laying brown eggs.

All of those "chance of 50%" and "chance of 25%" are because I don't know if the blue-egg bird has one blue egg gene (goes to 50% of chicks) or two blue egg genes (goes to 100% of chicks.) So I listed both possibilities.

This whole breeding for egg color thing is confusing.

I handle it by figuring blue eggs (vs. not-blue), and then separately figuring brown eggs (vs. not-brown = white eggs), and then combining the results.
Blue and not-brown is blue
Blue and brown is green
not-blue and not-brown is white
not-blue and brown is brown

There are actually mutiple genes that affect the shade of brown, but they mostly average out so crossing light x dark gives a medium shade. One specific gene is sex-linked, so a hen can inherit it from her father but from her mother. That one makes eggs white or very pale brown. I accounted for that in my predictions for the California White rooster.

Wow thanks so much! This was very informative.
