Blue brahma eggs

[CCUK]

I am trying a Brahma EE Cross right now. The eggs will hatch next week

You'll have too let us know how you get on! This could be quite a fun and interesting venture!

I also did a Cochin and maran cross

I also did a Cochin and maran cross

How did they turn out?

So if first generation would lay green eggs, if I was to have a cockeral from them and then put it with a purebred Araucana would the second generation eggs be more towards blue or just a lighter shade of green?

I think you would get closer to a blue egg, but it would still be fairly green.
If my thinking is correct, it will take you several generations of breeding in more Araucana to get a blue egg. By that point you will have a bird that probably won't resemble a Brahma.

Although, I am curious about the process of you use a Brahma hen and Araucana rooster. Since hens only have 1 copy of the egg color gene, they can only pass it on to 50% of their offspring. The males, I believe.
So I wonder, then, if the F1 females would only carry a blue egg gene, or if it would take less backbreeding to establish a blue egg layer.

They would most likely be some shade of green. It would take quite a few generations to try to breed the brown out and quite possibly it may not happen. This is the reason that people wanting to bring the blue color to heir chosen breed, choose a breed that lays white eggs to start. Crossing a blue egg layer with a white egg layer gives light blue eggs in the F1 generation.

So that would be 2nd generation before you could really see the result?

Since hens only have 1 copy of the egg color gene

The egg color genes are not sex linked which means that both hens and roosters have a pair of egg color genes when it comes to the blue gene. They can also have a pair of each of the possible brown egg color genes.
