I talked to the person who I got my birds from. He thinks the pen my original chicks came from was BLC X BLC. He did get BC from that pen with no white. I will p.m you!because of sex linked genes .
the hen only passes her sex linked genes to her sons only .
the rooster will passes his sex linked genes to both of his progeny .
using BC rooster as a breeder over BLC hens will maintain the uniform under fluff and plumage . plus the quality of the copper .
the Blue gene seem to dilute the copper ,especially if line bred .the Blue and the copper will get mashed out with time .
breeding the Blue is the most complicated work a person can do . because the Blue never breed true . need Black to maintain it ,
I have over 50 BLC pullets no 2 of them look a same . if I had 50 BC will be different story .they will look impressive uniform Black .
No more BLC breeding for me , only keeping few for a look that all . I will breed BC from them and I will sale them next year . lot people after them ,not me .
