it sounds like your red sex link carries dominant white, If this is so, then some of the chicks will be white or white with black spots. The adult females
will be white with some red on their bodies. The red usually shows the most on the head and hackles and decreases toward the tail end of the bird. The white males may or may not show red on the shoulders and back. The rest of the adult offspring will be black and showing red. The amount of red the offspring show can vary.
males may look like the male below
