Genetics Question: Birchen & Silver Duckwing

[Dirt_Farm]

This is Poppy. He's 3 months old. His dad is a Birchen OEGB and his mom is a Silver Duckwing OEGB. I haven't wrapped my head around chicken genetics yet so I'm not sure what he would be considered. His coloring is different than his Birchen dad, and I think that doesn't necessarily mean he's a Silver Duckwing. Is he old enough to tell what he is or what he could be?

He is still technically birchen, but thanks to his duckwing father he has lots of lacing leakage on his breast.
His lacing is just a bit more than is natural on a birchen bird.

Thank you Amer! I appreciate the response. His lacing is one of my favorite things about him, but it was throwing me off on if he was a birchen.
