Regarding breeding solid Blues or Blacks to Coppers...
I'm confused here as well....are we talking about breeding pure Blues to Blue Copper or Black Coppers?
Are they not genetically different? I've thought that this was not good practice as they are totally different genotypes?
I've read many sources that say not to mix the two varieties, yet see some are doing this to help egg color in the B/B/S.
Some may appear to be solid blue or black, but are carrying the BCM genes, and are seeing copper leaking?
If doing so, how many generations is needed to breed out the BCM? Is ON, who wants no coppering, seeing an incomplete
crossing with coppering bleeding through? Would ON be better served by continually breeding those with no copper, or by
incorporating genetically solid B/B/S?
Hopefully, the genetics experts will give us some help on this.
