I hatched some eggs from a blue Silkie and this IDEAL girl (she was a mis-sexed 'male added for warmth'):
I guess she'd've been called an EE, the other 'added for warmth' chicks looked EE-ish (multi-colored, bearded, willow legs).
And got a couple of these:
Mated those SFGE girls back to a splash Silkie and got these:
They lay blue-green eggs as well.
That's not what you were asking for though. Unless your EE girl carries the silkie feather gene, you won't get silkie feathering the first generation.
I didn't take any pics of the regular feathered ones.
Good luck! I bet they'll be awesome!
