yes easier with the same loft ,, if you can build a make shift aviary , separate cocks and hens [ with separated aviary] and as they are yearlings and probably not going to do the longer races later in the year, would leave them like that till jan[ thats if your racing w,hood,] then pair up , and when their sitting , take the aviary away, you shouldnt have any problems ,as far as them homing hope that helps mate.
