Yes, she's always had some mottling but her recent molt has really brought out more mottling. Her parents were birchen, but my ladies sometimes end up darker than I like sometimes, I'm working on that. Even so, I still keep the black hens that have good confirmation. Her mother is a birchen with much less mottling, so I chalked it up to parasitic white. If mottling is a simple recessive, could there be any expression of it if one was a carrier on the hen?first .she is gorgeous .great body type and good eyes color .
is she always has a mottled spot on her ,or just when she become more older?
she carries a Mottled gene { mo } for sure , but for the mottled pattern to appear she need to have both pair of mo genes . so her parent had 1 gene each .
I m also thinking she is more of black unicolor , Extended black not Birchen.
the white chicks can come out of any hen ,but the rooster has to have one gene too of the recessive white .
need a lot test mating to purify your line .
