Easter Eggers ~ Americana ~What Factors =What Colored Eggs~ Post Yours

[Manningjw]

I have an Easter Egger, I posted the pic of her on another thread,(on the right) and someone estimated she's about 15 weeks old.
Will an EE lay at 20 weeks like my others do, or will I have to wait a lot longer, since the light is slowly fading? Any EE tips?

Our EEs started laying eggs I think at 22-26 weeks old. My most recent hybrid Ameraucana/White Leghorn/Black Australorp started around 20 weeks old. It can very as EEs are mutts and who knows what went into them.

To the question posed by the OP:

Pea Comb gene has been suggested to be closely linked on the same chromosome as Blue Egg shell gene of the Ameraucana/EE lineage. Typically these traits are inherited together though not always which is why if you have an EE or a cross of an EE/Ameraucana whose parents laid a blue egg and your hen has a pea comb more than likely it will lay blue or green eggs. Blue vs green is much harder to determine and outward appearance wont tell you anything really - you have to know the lineage or just wait 24 weeks and find out .

There is no set outward physical appearance that will determine or even hint at egg color beyond that. Case in point being the Cream Legbars do not even have pea combs or muffs but will lay a blue egg.

Not just suggested, MAPPED to be 4.3 map units apart. Each map unit corresponds to approximatedy 1% chance of not being linked in inhertance. Thus there is a 95.6% chance of both the P and O genes being inherited together (and 4.3% chance that only one will be inherited).

Cool! Thanks for sharing your knowledge. I didn't realize that Amercauna genes were mapped and they were also able to determine the specific location of the gene - VERY cool.

I remember someone saying that there was a 95% chance that they were inherited together, I used that as a guide for future breeding projects and so far so good.

I am courteous do their eggs show color when they first start laying?

Yes, if she lays a blue egg for her first one, shell always lay blue, the next one won't be pink, and vice versa. They are a very fun chicken to have.

My Americauna lays green eggs.

My older girl is very plain jane and lays a light brown egg.

Younger girl is half EE, half polish, and 100% nuts. Light blue egg.

Reviving this thread to subscribe! I hope to post pictures of my EE eggs within the next month and really enjoy seeing the colors of both the birds and the eggs.

I really hope to get some of those pretty green ones like reckless posted!

Anybody ever wind up with an EE with a single comb that laid coloured eggs? I have some 25% ameraucana/75% australorp pullets, just wondering if any of the single-combed girls might lay green.
