The general concensus amonst silkie breeders is that tha vast amjority of silkies will not choose to roost. An occasional few will, and they can sometimes be taught to roost--either by regularly placing them on a roost or by housing them with other breeds that have and use roosts. More of my boys will roost than will my girls, who are rarely interested, but then I have one girl who roosts higher than her polish rooster coopmate.
