mgauv For the last many years I have only raised silkies. But from what I remember of the buff orps, rho-isl- reds and others, the white is the only female in the bunch...The combs being bulkier, bumpy/ pebbly looking are male traits. Females have a thin, smooth comb that is small in nature. All colored males will have feathers that start to show iridescent coloring of blues and greens on their tails, wings, necks. White males can show a shine to their male plumage as they mature.
