This isn't the first egg I've found buried whole in my planters!
It's the work of a fox, who being very dexterous can handle, bury and dig up eggs without breaking them.
I'm just glad I didn't break into it with the trowel!
Where on earth it's finding the eggs .. but there's evidence to be found around the garden.
There's no farm nearby, or who keeps chickens? .. a neighbour must be putting them out especially for the opportunist thief.
It stores them away for the next time it's hungry.
I wonder where it's next cache will be found?
