I was thinking the same thing. I do have a topic I'd like to "revisit." I've thought and pondered the brief discussion about Birchens, specifically my Birchens and I'd really like to discuss this further so that I can make the needed changes in my direction.
Even before this following quote, Tom commented that the pattern appeared "incomplete" on my hens. Then sjarvis stated in the quote below that I might consider using an actual Birchen to set the color - I'm thinking this also means the pattern, maybe even more specifically so. So does this mean that my girls are not carrying the Birchen gene and just kind of LOOK like Birchens? Does it also mean that if they were actually ER/ER and the roo the same, then the pattern would be predictably Birchen, but as you stated sjarvis, I could skip all of the culling for color/pattern?

It sounds like it is necessary to practice double breeding to get the correct pattern on the Columbians. I have Partridges and I intend to double breed them, but so far I don't have enough offspring to select from. I'm hatching every eggs I can get from them and the Birchens, but hatch rate has been really bad this year.
The Columbian Pattern can be single mated with a fair amount of success, but is best dowuble mated. Have you considered bringing in an actual Birchen to set the color, and pattern as well actual Birchen genetically? It would take some time to get back to good Cochin Type but would eliminate all the color culls in teh process.

show me your origina question with pics, I may be able to help,

I think we need to be careful when discussing the "pattern" in Birchens. It's probably just a matter of semantics, but it can be confusing. There are only three pattern genes: Pg (Pattern Gene), B (Barring Gene), and Mo (Mottling Gene).
Birchen does NOT have any pattern genes. And Birchen is not a gene - it is the allele ER. The Birchen Variety is the basic silver variety on the ER allele, just as Brown Red is the basic gold/red variety on the ER allele.
The proper genetic code for (Silver) Birchen is ER/ER S/S ap+/ap+.
The proper genetic code for Brown Red is ER/ER s+/s+ Ap/Ap.

I asked this in a separte thread.....but wanted to revisit it here. How do I get dominant white into large fowl cochins? Was told to add a bird in with dominant white, but not leghorns as they also have some other thing that will cause issues.
What would be the "best" bird to add in that will create the least amount of problems? Or is there any other way to get dominant white in there?

Correct.. maybe he is talking about the natural birchen pattern that is a mistery to all of us... you know the kind that can look like gold or white lacing depending on the background(Silver of Gold)

get it from other close birds like, brahma, Dan P is working buff laced brahma and they have dominant white in them, do you want to have a solid white bird or what are your goals..?

I want a "paint cochin". I have crossed leghorns and cochins.....and ended up with that coloring in the pullets. Not sure what would happen when crossed back to the cochin rooster a few times. Obviously a leghorn/cochin doesn't look all that cochin. Like a feather legged leghorn mix
I want to make a full sized large fowl "paint" cochin. White with black spots.

well since you already started your project and see what's the outcome, I believe your next option is to breed back to Cohin, and repete until you have body and type set as the color you are wanting is dominant over what cochins have...
