Hey Marvin, @nicalandia
White hot question from the Sussex world. Some say LS can have grey in the underfluff. I say no. Must be white to the skin. Can youthinky of any reason how grey underfluff could happen in bird (LS) whose formula was eWh/eWh S/S Co/Co ???
Thanks, Karen
Based on pure genetics and knowing how the eWh/eWh S/S Co/Co combination works I would say with certainty that White Underfulff is the only outcome
