OH Mark! I'm so happy you got Naked Necks!
Yaay for Naked Necks!
They all came from blue, splash, or black hens.
You know the chicks from the F eggs are blue and black Frizz hens w/ lemon blue Cochin roo.
The NNF eggs were from the blue green-egger hens w/ splash NN Frizz roo. I'd bet that's your splash NN chick --- is she bigger than the others?
The eggs marked BNN were from little blue, splash, or black Naked Neck hens and no clue who is responsible for fertilizing the eggs. Possibilities are NN Cochin roo, NN Silkie roo, Serama roo. They are separated now, but it was a big 'mixed pen'.
All of them EXCEPT the ones from the Frizzle pen have a chance (a slim chance) of being silkie-feathered --- because they all have Silkie somewhere in their background (all my Naked Necks started as Turken x Silkie crosses).
The hens are all regular feathered, but could be carrying the silkie feather gene. Paired with a roo that is carrying the silkie feather gene, they could have silkie feathered chicks.
