Yellow Speckled Sussex?

[RoostersAreAwesome]

It's suppose to be yellow shanks. Flesh color is a off shoot. But not white or slate colored legs.

Her pattern is uneven also.

If you look at SFHs on hatchery websites, you’ll see many with uneven patterns and the wrong leg color.

Just one example.

She's likely a barnyard mix.
