Blue egg genes X brown egg genes = ?? egg

post #1 of 9
Thread Starter 

Does anyone have experience or photos of what a blue egg layer gene crossed with a brown egg layer will produce?  In this case, a Cream Legbar with Red Rangers, Orpingtons, and Austrolorps specifically.  
When I cross these hens with a Marans I get beautiful earth-tone clay eggs, so I'm curious about the other end of the spectrum!

Usually best to expect varying shades of green.

Most of the time the darker brown eggs when crossed with blue egg genes will be darker green and lighter brown will light green...they are two colors of egg shell blue and white ..brown is a top coat..blue shell is dominant and when coated with brown it looks green so the darker the coating of brown u get a more deeper green

Huh!  I didn't know!  I cross my Ameraucanas with my Marans rooster for OEs that produce very dark rich earthy green eggs.   I am eager to raise a few hens and see what they produce with my new cream legbar roo!    :weee

Blue egg layers X brown egg layers (like the three breeds mentioned in your post) will lay eggs in varying shades of green depending on the darkness of the brown egg genes. Blue egg layers X chocolate egg (very dark brown egg) layers will lay olive green eggs.

Hum.  What about a white egg X blue egg?

You will get very pale blue eggs.

actually you can get tinted from blue x white, if the blue isn't pure for the blue eggshell gene.  I full well the conventional reply of blue eggs being a result of blue eggshell gene on a white egg but this happens often enough not to be an exception.

 

some white eggers(certain leghorn lines in particular) have a gene that actively represses any eggshell color, making the blue eggs really pale or even just barely off white.

My only white egg layer is a one-eyed cross-beaked (result from factory clipping it, it grew back deformed- not genetic) brown leghorn.  She's 6y/o now and only lays about 2do eggs a year.  She's a really cool little chicken (and has saved her own life more than once- a trait I appreciate) and I want to perpetuate her genes.  I hatched out 10 of her chicks last year and a weasel ate them all at 6 weeks :he 
Anywho, that is why I asked about the white!  I have blue and black copper marans roosters and am adding the cream legbar.  I have so many colorful layers that it's actually exciting to get a white egg every few days xD
