That is stress barring.... which is pretty bad if you have that much of it.... If I am wrong about that sell them for $1000 a pair as mottled orpingtons and buy more blacks to replace all of yours and feel lucky for getting $500 birds instead of $50-100
You would have to keep breeding Buff Laced to Buff Laced and select for the birds that dont have the blue specks showing in what should be the white part for breeders. It would take several generations.
I personally am using a Choc split male in my Black breeding this year, I personally don't see any wrong in having birds with hidden genes if it wont affect the flock overall, just as Wyandotte breeders have SC birds show up, and some lines of black have whites come out. I just see it as...
The ones that have the gold in their necks probably have only one dose of the gold gene, where as the ones with the red have two doses. The gold gene is what makes a bird any of the colors from Buff to the deep mahogany red, there are other genes that are with it that creates the depth or...
Typically the genetics would be different. From my understanding blacks typically carry the Gold gene whereas blues should have the silver gene to improve lacing. Also some blacks that come from blues that have good lacing will have a good green sheen with a lacing of flat black around the...
It looks like a mix of different varieties to me, wouldn't breed true. But Shaffer is right, it most closely resembles the silver penciled coloring. For Birchen the bird would be black with silver in the hackles.
The tail angle according to the US standard should be 25 deg for males and 15 for females. In the UK there is no set angle for the tail, it just should be short and high but not squirrel tail.
