Thanks for the help.
Hi, thanks for your interest in Cream Legbars. Do you have pics of your new girls to share?
While not desirable, in my experience, CL may have only one blue eggshell gene (heterozygous); leaving green/brown out of this equation on purpose. This may not be the result of any recent crosses, but a result of shaking out all the variables when the birds were imported. It is noted that there are significantly bluer eggshells in some UK lines, so for whatever reason we are not necessarily seeing the deepest saturation of blue here even when the birds are understood to be homozygous for blue (have 2 blue eggshell genes).
As mentioned by @ChicKat , if both the hen and the rooster have only one blue eggshell gene, 25% of their offspring will only have the white eggshell gene. So it's possible for the hens to look like CL but not lay a blue egg. Again, this is not desirable and if all other appearances are per the Standard, with some diligence you could breed your flock back to homozygous for the blue. Or, just enjoy the birds at hand and get a separate CL breeding flock to maintain the blue eggshell gene.
As it turns out, I recently found a more saturated color pullet egg, but I honestly don't know if my CL or OE is laying it...
The 3 eggs along the top are from 2 CL sisters. The light blue is a pretty typical color, the one on the right is a little more green than any others I have had.
The pullet eggs along the bottom are the first eggs of one pullet, and more closely resemble the egg color of a Wheaten Ameraucana I had at one time.
(fyi - the eggs are not washed, and I did not use a flash, the lighting is from a skylight).
