Partridge Orpington Colour Question

[steynig]

Hi,

I need help establishing why this Partridge Orpington hen is a bit too dark on her saddle/ back? What genes can cause this, my guess is not Melanin since that will give her slated/ dark legs.

Can it be a columbian restricting gene perhaps?

Correct colour below:

Wish I could help you.....

You might want to move this to the "breeds, genetics and showing" section. That's where most of the genetic gurus hang out. You'll probably get a better answer over there.
