I was thinking Sultan too. I bought top knot chicks this spring and they are all gold laced polish.Since you said the white one with feathered feet has a top knot it should be a sultan. Does it have 5 toes on each foot? The other two look like a blue polish and a splash polish. Your feed store probably got them from Privett, they're the only hatchery I can think of that sells blue polish bantams.
