Straight comb with green egg

[Wiljam09]

I watched her lay this, she is a second generation. Her grandmother was isa brown and grandfather Isabel Ameraucana. Her dad was full bc marans so I guess people would call her back cross 1.

I think I have one other straight comb hen that lays a green egg (carries blue shell) thought this was interesting. I watched her lay it so I am certain.

Back Cross would be breeding back to an ISA Brown, or the Ameraucana, since those are the original cross from the beginning.

She would be an F2(Second Generation) cross.

Thank you for clarification, that makes sense.

If I have a male white leghorn, I think I may breed them to each other to hatch offspring. I was reading that the offspring would have a higher chance of carrying blue egg gene with straight comb. Supposedly this cross keeping blue egg gene was only 3% but further crosses moving forward would be better?

By chance I actually do have a white leghorn rooster currently. It would be interesting to create a blue egg straight comb dominant white chicken as the offspring.

I don't know tons about egg color, I mostly breed for feather color/patterns, & other traits that make every bird unique.

With that cross, you should get about a 50/50 split of chicks that inherit the blue egg gene, and chicks that do not inherit the blue egg gene.

With both parents having single (straight) comb, all chicks will have single comb.

Yes, there was a very small chance of getting single comb/blue egg when you started with pea comb/blue egg, because of the way the genes are linked. But now you have one chicken with a linkage of not-pea comb with the blue egg gene, so that set of genes will be inherited together for most of her offspring. (That's the same gene linkage that Cream Legbars have, not-pea comb with blue egg.)

If you want actual blue eggs (not green), it may take a few generations of crossing to Leghorn. If you want eggs any shade of blue or green, you should be able to get some in the first generation of breeding this hen to your Leghorn rooster.
