Also if you would rather you can buy a small incubator for 1-3 eggs on e-bay and move the single to it to finish out. If you order in the next day or two you should get it in time.
(((put the silkie eggs in ur bator on the egg crate))). and on day 18 set them out of the crate on the wire floor of the bator.
the crate just keeps the ones that hatch on a earlyer date from rolling the later dated eggs all over the bator.
i dont know everything but i realy dont think the egg ya got outa the frig will hatch.but i have been wrong .good luck.
