Thanks for all quick replys, the reason i only fly natural is i only have a small loft with two sections, i am not sure if i can fly widowhood if the cocks can see the hens ive just started keeping racing pigions and havent started racing yet, i previousally had compertition birmgham rollers which i kept cocks and hens together, i plan to race next season but i need to know which system to use with my limited space, they all get good amounts of food, they are all healthy, they always beat me home. Thanks
