That is correct.

Green is a blue egg with the brown "paint sprayer". Storm, Maizie and Pippa all lay green eggs here. Surprisingly, Storm's daughters, Cumulo and Nimbus (both black from her blue) both lay brown eggs. Maizie/Pippa (not sure which one) have offspring in Tuff, by way of Horus, son of Cheetah and Nellie (Hamburg: white, brown leghorn: white).

Storm's parentage is Blue laced red wyandotte (brown egg) crossed with olive egger (cream legbar x cuckoo marans). Storm lays green eggs with brown spots. I suspect it came down to 1 gene for blue egg, 1 gene for white egg, and Cumulo and Nimbus both got the white egg gene instead of the blue. And got brown from 1 or both parents. I have 1 brown egg layer that is a richer, darker tone than the others, so one of the 2 girls likely pulled some of the Marans with it. (When genes get into throwback stuff like Storm's 3 feather crest and Cumulo's 5-7 feather crest, it starts getting really convoluted).

I have zero clue what Tuff's carrying for egg color as he hasn't had offspring yet. He could potentially have the recessive white, blue (without the brown sprayer), green (like the egg he hatched from) or brown (missing the blue like Cumulo and Nimbus did).

Ain't multigenerational genetics complicated?

Time to let thing settle in my head again.
Too late for me

Extremes of anything are not good 😞

I meant to ask how your test went yesterday.
TY ~ tests are all done so the hospital pre-surgery yesterday was mostly ins paperwork & registration about 7 pgs. Then an RN surgery nurse goes over disinfectant body wash instructions. Basically don't eat, don't take vitamins/supplements, no pain-killers like aspirin etc, see the surgeon the day before surgery, RN swabbed the nostrils, I must read 4 pgs of surgery day instructions & commit myself to no-sleep pain for the next 5 days cuz I can't have my pain-reducing natural Magnesium supplements. I was up 6 times last night from excruciating pain so that meant DH was up w/me too. I think the pain will kill me (& DH) before the surgery will :(

So, from reading these articles, an original Blue CAN come from a Black parent if the black parent has a diluted black gene? I know Blue x Splash or Blue x Blue make some Blue offspring but the original Blue came from a Black parent from what I'm reading? Now I positively am certain why I never delved into genetics!
No. If the diluted black gene is present, it is VISIBLE and the bird is blue or splash (2 copies). It's possible (likely) it started that way as a genetic mutation/defect, but relying on that when purposefully breeding, doesn't work very well.

Breeding Black and Blue can get Blue 50% of the time BECAUSE the Blue comes from the Blue parent.

Black can be thought of as NOT Blue. For Blue to be seen, it HAS to be one Blue and one Not Blue. Splash is one Blue and one Blue. Black is one Not Blue and one Not Blue


Going back to my birds

PITA and Blanche are both Blue and Blue.
Therefore ALL their offspring will get Blue from mama. What each of those offspring get from papa, depends upon papa. Cheetah (skipping the other colors he has) is Not Blue and Not Blue.

All of his offspring will get Not Blue from him.
Lark and Indigo show Blue because they have to be Not Blue AND Blue.

when both girls got the Not Blue from their daddy, they also got some leakage of other colors in the orange.

Zulu, Cheetah's offspring by one of his blue daughters got Not Blue (with other colors) and Blue (with other colors)

He also got the rooster color vibrancy of being ZZ (roo genetics) rather than the ZW of hen genetics. The Z tends to carry much of the color, explaining why roos are more vibrant than hens (double whammy). Would have been interesting to see how his genetics would have played out, but due to the presence of his mother, grandmother and father/grandfather, he was on the rehome/freezer list.

Still wondering how he got willow green legs from grandparents' blue legs....but from what I've read, legs genetics are semi-unpredictable.

As best I can understand...the original blue chicken is an accident from a black flock...which is not something originally able to be bred? But after getting a surprise blue it can be used to breed within the BBS breeding chart to get more blues & splashes? I love blue chickens so I'm a broken record about blue origins ❤️

It has always been hard for me to find blue birds in breeds I wanted.
