These are my mixed girls and was wondering does she have a feather pattern that's identifiable. I'm asking because on both girls there's a white line running down the middle.
They're both mixed color/patterns.
The stripe is part of feather pattern that goes all the way back to the wild type (duckwing) pattern. Its just part of the camouflage pattern for the females.
Its on many patterns and mixed patterns. Very common.
