Marans question

[Hazel feather]

I’ve got a silver black ( birchen ) split silver salmon Marans rooster. His father was a silver salmon and mum was a silver black . I’ve also got a silver black split silver salmon hen she is a dark blue colour though. So my question is what colour would their offspring be if I bred them ?
Thanks in advance !

It's really weird that they call silver duckwing silver salmon in Marans, but here's your answer.

Thank you for the reply!
