My niece sent me this article
https://insteading.com/blog/chickens-that-lay-blue-eggs/?ck_subscriber_id=609094710
If you look at it, you will see that they have an "Opal" -- as a blue-egg layer.
As I recall, only Candace had those, so I suspect that particular chicken traces back to her. How very cool is that? Also a side note the bird they are saying is a cream legbar (cockerel) -- looks about unrecognizable
to me as a CL. Kind of sad what the breed as become IMO (of course that probably makes me a far outlier

) since the breed first arrived in the USA in 2011 and became distributed out in 2012--so 6-years of selective breeding has done that to them.
If you don't want to click to the article, then here's the Opal photg.
Mine are similar in color and pattern but I've bred out the crests, because I didn't like want they did to the male's combs....there was never enough real estate on the chicken's head to have both a crest and a nice comb (very few at any rate)---I was pretty fortunate with my CLs because I kept crests SMALL while others were aiming for the look of the Polish breed. LOL.
Okay -- should I continue phase II of the project on this thread or start a new one for the on-gong future activity.

It's not like there a too few threads on BYC....but going forward won't be as much about the genetics of getting to the autosexing Lavender Patterned Isabel Duckwing-Barred (It's a mouth-full) as about trying to sustain and improve the variety. Any thoughts?
