Yes, the blacks are from a black only pen. 2 really nice boys with no leakage over the hens. Some, but not all of the birds come from black/black breeding themselves.
I have 12+ eggs from my black pen. Fertility has been great in this pen and have been hatching some nice chicks. Parent stock from Three Cedars, Murano and my own breeding.
Also have 12 blue splash eggs and can put eggs from the black pen as extras. Parent stock from Obsessively Silkie...
