Don't make assumptions about which e alleles are making the best BCW. My birds have at least eb, ER and ewh. Charcoal may be the gene that makes BCW but as far as I know it not been mapped.
Good. I have culled this year's chicks down to about 3 dozen. They are 2 to 4 months old. Every one of this year's hatches fall into some sore if cross. Therefore none have everything I'm looking for, but many are promising.
The goal for the Silver Laced x BCW was not to clean the bodies of black. That cross is to improve vigor and type. Because BCW are poor in both. The cross with buff Orpingtons was to get the right genes for clean, no black bodies. But Orpington have a completely different type which must be...
Thanks for such a detailed reply. I agree with your analysis. One thing you didn't mention is these crossed birds will have excellent vigor. They can be bred back to BCW and improvement should follow. I think these crosses are not likely to improve color, but you should be able select back to...
