After looking at the pictures of the birds in the pen, one of the females that looks like the bird we are discussing  is the mother. The birds carry a restricter called  dark brown. Dark brown is the only restrictor that I know of that will work on extended black. Also birds that carry dark brown can have lacing, spangling or autosomal barring depending on the bird's genetic makeup. Sometimes birds will show two or three of the secondary color patterns on one bird. It is possible that this bird is also carrying the columbian restricter also.  Many black birds carry the pattern gene also- the female  inherited one pattern gene from the father.
The females in the picture and the bird under discussion all look like a buff X black cross.
The bird in question does not carry dunn.
If you want to produce more of the bird cross a buff orpington with a black orpington.
You can not make good lacing on the extended black or anything close to lacing on the wheaten allele. The birchen allele will have to be introduced to make a gold laced feather. Dark brown will just produce black tailed red birds on wheaten; add columbian and you get buff.
