Marsbar Chick and autosexing

[house1917]

that’s a fancy bit of software! Looks like I may have all cockerels then - not a great start to getting a rainbow of eggs in my basket

Oh, this calculator isn't the best user interface, but it's addictive for us chicken lovers!! This spring I'm loading some of my favorite purebred eggs into the incubator- wheaten marans and welsummers. But also some crosses- olive eggers black copper marans and welsummers, and BCMs or Ayam Cemani on 'purebred' hens (Isbar, EEs, RIRs, etc). With all the combs, leg colors, and color combos, I'm hoping this calculator helps me determine heritage!

I bought the eggs on eBay and the breeder stated they were CL females running with a marans, so I think not. They seller has a good reputation.

Now that I look back, it's been a few years, the males will be barred.

Actually looking at the calculator results - is it the other way round? Is the pullet barred

If you scroll down under the pictures, past all the genetics table, you'll see a white "Calculate Crossing" -- that will give you the offspring of the BCM/Crele paring!

High value web site, just a funky interface.

This would be a sexlink cross not autosexing. males will have a white dot on their head

Yep, they all turned out to be boys. No green eggs for me!!

Decided to go for some marsbar chicks for their olive eggs (cross between Cream Legbar (mum) and French Copper Marans (dad). When the first one hatched it had such clear autosexing markings of a female cream legbar, we were pretty confident it was going to be a girl, however, 3 and half weeks later, it seems that Marcie may in fact be Martin...I'm guessing autosexing isn't so reliable when crossing.
View attachment 3464592View attachment 3464593(We have 2 more which are 10 days younger, but the markings weren't as clear so the jury is still out on those)

I've read:
Male = Barring
Female = Solidish Black/no barring
And both carry dark olive egger genes, but only 1/2 chance of blue-egged 2nd generation genetic chicks.
But what's their specific genetic chances M/F of passing darker brown bloom genes to their next generation chicks?

But some of these roos' babies WILL have green/olive eggs. (I just don't know the PunnettSquare percentages.)
