Research obviously is necessary to determine what is the correct season, but my limited memories of when you get the ducklings tend toward roses in bloom in the vicinity, rather than apple trees, daffodils, and crocuses. . . .
So, do I rework the little details of the plants? They were only local color.
Or have the heroine conclude that time is odd in this location? It's not as if it would be the only odd thing -- the ducks are gold.
And I haven't even done the research yet. Perhaps it's just an early clutch.
