I have a rooster from a red sex link/white leghorn hen cross. He has spots the color of a RIR[just a feather here and there]and a yellow hackle and saddle like his daddy.His featchers are like a white leghorn ,tall comb ,kind of skinny looking,and a little schitzo.I didnt have a hen but,they will probably have a lot more red in there color[from grand pa and grandma]than the roo.You just might be able to sex them quite early. Good luck
