Breed Color Question

[LilChickens2]

Not sure if you can help with this question:
I have a group of “red” bantam Cochins. They are in their own pen and never intermingle. One of the hens I don’t think is red because of the chicks I get (pictured). What color would she be to get that color mix pictured? (Originally I had just chicks hatching all red, now they hatch red or “red partridge” and turn into this color shown.

What would the hen be (color) and what would this mix be called (color?)

Thank you!

She probably has partridge in her back ground, rooster could too. Cochins are a breed where most colors can be seen, so people will mix them up more often when breeding.

Thank you. Now just to figure out who is doing it. Hopefully it is not the rooster too.

Partridge is recessive, so both parents have to carry it for it to be shown in the offspring.
