They're expired because you cannot obtain one without breeding two snowflakes together. An available dragon can be bred using hybrid, or occasionally other limited dragons. 3rd and 4th snowflakes require 1st and 2nd, which are no longer obtainable if you didn't get them in the event. The snowflake page says expired anyway.
