White patch on Pharoah color?

[Rhiannon_In_Nature]

Anybody else have or have seen a Pharaoh-colored Coturnix with a random white patch of feathers? I have a hen with a small patch of white feathers on her chest. Is this similar to a tuxedo? Haven't seen a tuxedo with Pharoah as the base color before.

It could be a mix of a Texas A & M and a Coturnix. That might be what caused the white spot.
