Questions about EE's, "Olive eggers", ect......

[cashdl]

I have a BCM roo in a pen with my blue egg laying easter eggers. I am setting eggs in the bator right and left. I hope by spring to have olive eggers than I will breed back to my araucanas.

could some one post a pic of the eggs produced by a hen who is half marans and half ameraucana?
I've read that you breed the 1/2&1/2 back to the marans roo as well to get the best olive color.....is that necessary?
Or will there be much of a color difference at all?

In this photo the Olive Green eggs come from a hen who is a cross between a Wheaten Marans Roo and a Wheaten Ameraucana hen. The light brown egg however comes from a hen who is the exact same mix so it's not guaranteed you'll get an Olive Egger from the mix.

Thanks for the pic bluedawg! hav u heard abt breeding the cross back to the marans roo? I just wonder what purpose that serves...do you know?

I have not heard anyone mention anything about that. So for me I guess that would mean just hatching out a few of my Olive eggs. Interesting

Doesn't make much sense thought that they would be darker, it's not like they'd ever get a double dose of brown coating

I could be missing something though.

Hi guys!
Just to clarify....I have a Marans roo and a good blue egg laying Ameraucana.
I am planning on breeding them in the next two months but, still have questions and a little confusion.
Once I breed the roo and hen do i need to breed the offspring back to the roo? If so what purpose does that serve? what are the chances that the offspring from the first cross will just lay olivve eggs? Good? Bad?
I need all the help I can get!
Thanks in advance!

Any F1 cross of a homozygous blue egger bird, and a dark egger bird will give you "olive eggers". No, you do not - unless you are unsatisfied with the F1 crosses' egg color. Crossing them back to a homozygous breed for white eggshells will give you less olive egger birds from the cross.

Using a punnet square, all F1 cross from a homozygous blue egger cross will make Bw chicks (using B for dominant blue eggshell color, and w for recessive white eggshell color. Brown is an "overlay" of color, not a shell color.)

Crossing the Bw F1 offspring with a ww rooster, using a punnet square will give you these choices - Bw, Bw, ww, ww. So, only 50% of those second crossing chicks will lay olive eggs; the other 50% will lay dark brown.

So if I understand correctly......the best scenario is to breed the ameraucana and marans roo for the olive eggers. That would be the only way to"guarantee" the offspring will lay olive eggs as opposed to breeding the crosses to each other and getting blue or brown egg layers?
Sorry for the confusion...never did well in genetics
