The Seramacauna

[RoostersAreAwesome]

True...

I’m not saying that’s what I would do, but if you want to save some time it could be a good idea.

Yes please! A tiny bird that lays itty blue/green eggs, has a muff, big chest, and the endless variety of colors and patterns. My dream bird!

Eggactly!

I have been thinking, and maybe the Seramacauna can be one of those breeds where it has two comb varieties. I'm thinking pea and straight.

There is a linkage between the gene for blue eggs and the gene for pea comb.
So you would probably need to also add the blue egg gene from a breed with blue eggs/not-pea comb. Cream Legbars are one such breed.

The linkage can have any combination. Examples:
Ameraucanas have blue egg/pea comb
Seramas have not-blue-egg/not-pea-comb
Cream Legbars have blue egg/not-pea-comb
Brahmas have not-blue-egg/pea comb

But whichever way the genes are linked, they tend to be inherited together. Crossovers (where the genes swap what they are linked with) are fairly rare. So if you start with the blue egg gene from Ameraucanas, linked with the pea comb gene, you can reasonably expect that all chicks with the blue egg gene will also have a pea comb.

You could breed the F1 crossed birds back to a Serama and test several dozen single comb females, hoping for a crossover (I've read the rate is about 5%, which is 1 in 20). I think crossing a Cream Legbar is probably easier.

I may just stick with pea comb
