I have a mixed flock, but this one’s unique?

[RoyalChick]

I have three of “Eagles” eggs in the incubator now so we’ll see what we get in 21 days or so

I agree. Our Blue Egger/Leghorn cross lays bright blue eggs, very similar looking to Eagles. I think Leghorn mother Blue Egger father is a good possibility as you mentioned earlier @SuperiorFarmsGirl

Cannot wait to see what comes out of those eggs you have in the incubator!

But the question is, whether the Leghorn/EE, or Ameraucana cross carry one, or two blue egg genes.
Still learning the colored egg genetics.

I'm not 100% sure, but I think a double dose of blue would result in a stronger blue, while single would give a sky blue, or very faint/almost white blue on a white egg.

Anyone here with experience can correct me if anything is wrong .

Great.

For a normal Leghorn that lays white eggs, none of their sons or daughters can ever have two blue egg genes. Any chick would inherit one not-blue gene from the Leghorn. The chick may inherit a blue gene or a not-blue gene from the other parent, depending on what genes the other parent gives.

So a Leghorn/EE cross can have a maximum of one blue egg gene, if it is a first generation cross. (But breeding two such crosses to each other could produce offspring with 2, 1, or 0 blue egg genes.)

I'm not 100% sure, but I think a double dose of blue would result in a stronger blue, while single would give a sky blue, or very faint/almost white blue on a white egg.

Some genes have a dose effect (example: BBS blue feather gene)
Some genes do not (example: rose comb)

Some people say that two blue genes make a bluer egg, and some people say 1 vs. 2 has no effect but that shade of blue is affected by other (unspecified) genes.

The fact that some people say one thing and some say the other is enough to convince me that it doesn't make a LARGE effect, but I don't know whether it has a small effect.

Okay, thanks.

People have mentioned their Leghorn/blue egger crosses lay bright blue eggs and even posted pics so I feel like shade is determined by other factors. Perhaps even diet????

 

[NagemTX]

There are Ameraucanas that have 2 of the blue egg gene and still lay a very light pale blue almost white egg. So having 2 of the gene doesn't always mean you will have the brightness blue or a deep blue egg.

Ok, chicken experts do you remember the leghorn eggs I hatched close to two weeks ago? Here they are….
They have the splash markings like eagle. But so far no neck markings/brown feathers.

Those specific markings (from heterozygous dominant white) are called paint. It’s unclear whether Eagle is paint, splash, or something else entirely.

Ok gotcha. Learning more and more everyday
