Daft Answer I know, but probably people collected them before the cows
were
led back into the fields - probably cows like them for breakfast too!

Even dafter answer: Because if you don't collect them early, there won't
be
any left by the time you get there, since they will have been collected by
those who did collect them early.

So that's why I can never find any, but I'm too lazy to get up early anyway.
