Silkies with the barring gene tend to have mottled skin and red combs. It's the bane of those trying to create cuckoo silkies. I had a splash hen that took me forever to figure out what the problem was with her mottled skin. The I hatched eggs from her and a blue rooster and it became obvious when she had blue cuckoo sons and splash ones with the same skin problem. I lost her to a hawk not long after.
And I'm wrong on the pairing results for the silkie rooster to EE hens. I looked up the pictures. The GIRLS had the black skin, the boys had the lighter skin that was more grey. Black skin is a sex linked trait. Since females only get one copy of it anyway anyway on the Z and they get that from their father. The sons get a Z gene from each parent.
Hmm now my brain is in gear some. So I guess that makes black skin incomplete dominant? The chicks are easily sexable by skin color though
Regular feathers. The silkie feathers are recessive.
