An ovoid puzzle

["martin butterfield" <>]

I have just been wandering in part of our property and came across the egg shown in the attachment.  It is full - whether fertile or not I am not sure.  My first thought was domestic chook, but the egg was located at least 500m from the nearest active chook house.  Also the egg looks rather too "pointy" for a chook.  To give an idea of size the barcoded tag next to it is 60mm long so it is a large egg.  The egg was under a tree but I couldn't see a nest in the tree, and the lowest branch was about 4m above the fairly hard ground.

 

Does anyone have any ideas (a) what species could have laid this and (b) how it got into this position. We have a good supply of foxes, raptors, currawongs and magpies but I cannot see why they carried it so far to deposit the egg on the ground without eating it.
