Someone explain this

[Mbrew]

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?

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

Update as the chick grows please?

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.

And a blue hen I don't have pictured yet

Full body pictures of the boys? I see one picture is of an immature bird.

Okay, that'll be appreciated.
