Zum Kuckuck

The eggs lay hidden in the nests. Each player has to find out where the 3 eggs of his color are located. Whoever has collected 3 "Nest cards", is allowed to take his eggs out of the nests. But, woe, you got the egg of a cuckoo! Each player who has collected 3 nest cards, is allowed to turn his 3 eggs over during his turn. Winner is the player with 3 found eggs.
