The rooster looks to have a tinge of red in his feathers.

Noticed it on the neck but saddle too.. chick looks like my mottled red

The first two chicks darkened down and had same colouring on back as yours

Second last pic very little mottling is there any other colouring in her, lovely flock

She just has the blue sheen mostly black, do you think she's the one that threw this color

Not knowing the full extent of the colouring in the hen or the roo would throw unusuals

Old picture of a Blue Partridge Silkie, just for comparison of color. Of course with partridge, it's gonna vary in shade, & pattern a bit.

Your chick is partridge based. Your mottled and blue adults patterns/colors would be dominant over partridge.
To get that chick the pattern gene would have to come from both sides of the parentage so your rooster and at least one hen carries partridge.
A hen like that can very easily hide that it's carrying it so it'll be hard to figure out which one is.
With only one rooster that's a no brainer but a rooster carrying it usually does show some color leakage. I couldn't tell if yours is or not.

I have bantam cochins. 3 black mottled & 1 blue hen, with a blue rooster. And I got this out of the incubator today. Where did this color come from?

This is a new color that just hatched from the same parents!
