Australorp rooster crossed with either RIR or sapphire gem

This one?View attachment 2740233

Is a RSL. Mystery solved. Good job @The Moonshiner. Flexing that brain.
So red sexlink chicks can feather in white? I have a few chicks right now feathering in white. They are an EE cross RSL. So the white is coming from the mothers, the RSL? Do you know if the cross remains white usually? I am just curious.

@The Moonshiner can help here. He explained this to me today, but of course my brain has a hard time retaining that sort of info.

Most all RSLs carry one copy of dominate white.
That's why they have white in their tails, wings and hackles instead of black like RIRs.
When crossed they have a 50/50 chance of passing on the dominate white gene. When bred to something black the black usually dominates the other genes but the dominate white covers black.
Of course one copy usually doesn't completely cover all the black so you can get the black specks like with austra whites or paint silkies.
Dominate white doesn't do much to cover gold tones so when crossing with anything that would show gold or red leakage that will show up later on the white chicks.

Thats makes so much sense! Thanks you so much.
