Silkies are no more seasonal layers than most breeds: In northern parts of the country that have significantly fewer hours of light in winter will cause most breeds to go on sabbatical. Where I am, the extreme summer heat is far more likley to cuase stress and for them to stop laying than winter lighting. Silkies lay just as frequently as any breed, except that they go broody often, during which time they do not lay. They will start again about 4-6 weeks after the chicks hatch. Mine usually do not lay until 9-13 months old.
