Empty

Poppy found this empty shell of an egg on our walk this morning.  It is the softest loveliest duck egg blue but quite small and I have no idea what sort of a bird would have laid it.  From what looked like remains of yolk on the inside, I am not sure anything hatched from it.

It will do for todays Mono Monday challenge of "Empty" set by 60plus, thanks for hosting!
