Colors of Silkies

[Ole Grumpy]

I'm new to Silkie breeding and new at all the colors out there of the Silkie breed so what color are these ?????

 

[Sonoran Silkies]

They are both sizzles, not silkies, and hteone on the left is a partridge cockerel. I need a better photo of the one on the right, but it looks grey, possibly with autosomal red on the shoulders.
