I have a few mixed colored silkies. I have a partidge with a silvish/grey head and neck a blue/black with gold highlights through out his body. I love the mixed color silkies all mine are just from a mixed color of 2 silkes very beautiful.
Yes the black chick will be black with some highlights I have a roo the same exact color.
Here is a picture of him infrount of him is what I call my grey/partidge. He is mostly black with some Dark blueish under tones and has like a red to a buff color highlights through out his body
Is the non-silkie feathered hen next to the babies their mother? (If so she must carry the silkie allele to have silkie feathered babies.) I would say that BB's markings will be like hers: rather partridge-ish, but not exactly. Too much dark to be a buff.
