Colour patterns?

[ChickenKeep01]

My cochin bantam just hatched 10 cochin frizzle crosses and can someone please tell me how 2 completely white parents got yellow chicks with some black dots, and black and brown stripes.
Sorry the photos aren't very good quality

If white cochins are dominant white, that could mask recessive colors, but they could be silver instead of dominant white. @Lady of McCamley might know about that a little better.

I honestly don't know if white Cochins are dominant, recessive, or silver...however even if dominant white, like a Leghorn, white simply masks a lot of colors and patterns.

Every breeder knows adding white brings trouble upon subsequent breedings as those genes remix, a lot of stuff crops up.

Think of white like a coat of paint over all the stuff underneath. When that paint wears away (enough genetic mixing chips away at the white genetics) other stuff miraculously shows up seemingly out of nowhere.

So 2 impure whites bred together will produce a lot of surprises especially further you go away from the original source.

In curiosity I did a search for color patterns in Cochins and got the following articles.

The first article shows how some birds look white but actually are, for lack of better term to keep it easy, "over patterned." Their edging takes over or a secondary color takes over.

This article has the answer to your question. White Bantam Cochins are usually recessive white, but can have dominant as well. Each presents its own problems. Breeding a RW to a non RW will trigger hidden colors.
