Duck wings yellow

[lkazma]

My female Pekin wings are yellow while my male is white she has been this way for a while now any suggestions are apprec

My female Pekin has light reddish/rusty colored wings which is due to our red clay dirt. Our male stands on her wings/back to breed with his dirty feed and has stained her wings and middle of her back.
Your girl has less area covered in the yellow than mine so it could be something different.
