Collecting eggs every morning was a chore no one wanted.
When I was 4 or 5, I used to get a nickel for finding as nest... as I learned a bit, I could gather the single eggs and "build" that nest myself, and by the time I figured out how my parrents could tell my nests from the real thing (size matters), the game was over and it simply became a morning chore, sans the nickel.
