If you cross a Black Copper Marans roo with...

[Bantam BCM]

I have an ee who lays green eggs and bred it with a marans rooster so what will those chicks be called can you help me?

How did your hatch go?
Did any feather out BCM dominant? How about egg coloring?

What if you have a BCM with a cream legbar? I both pullets and roosters of both breeds. Is it better to mix one way or another?

Legbar/BCM and egg

ayam cemani and BCM she had a tannish brown egg.

Rooster is BCM mixed with LO/blue Isbar/and blue cochin. He came out looking all BCM

What if the Roo is an Americana and the hens are Black Copper Marans? Does the same theory apply? This is the situation I currently have going on.

Americanas or Americauna? Americana are basically EEs, so what the Americana roo x BCM female descendant egg color will be depends on what genes the roo passes on. The BCM will only pass on genes for brown egg color. The Americana could pass on genes for blue eggs, brown eggs, or green (there are many genes responsible for brown eggs, but only one responsible for blue, if the roo has any brown egg genes at all, some of them will usually go the progeny with or without the blue egg gene - it's quite complex genetically). If the progeny gets at least one gene for blue eggs, they will lay green or olive depending on the amount and type of genes they have for brown eggs. Check out the genetics forum, cool stuff on there.

An Americana is a mix breed chicken that could have 0,1or 2 copies of the blue egg gene. Since roosters don’t lay eggs there is not an easy way to know his genes you could have a DNA test done or test breed him to several hens then grow out a bunch of his daughters to laying age and observe their egg color to determine what his most likely genetic are.

Thank you for this detailed explanation. Mine are EE's. I'm trying to figure all this science out. Who knew chickens could be so complicated but in a fun way.

I breed meat birds and layers for fun and for dinner. It's fun to play with the genetics without needing a large or commercial size budget, and any that I don't keep or that don't show desired traits are not wasted, either through rehoming or freezer camp.
