Minecraft wiki entry for End_survival, associated text: The player should also collect the dragon egg from the top of the portal. Before collecting it, the player should cover the portal with blocks, so when it drops it will not land in the portal and get sent to the Overworld world spawn point. After that, do not mine it. If the player does, the egg will teleport away. One way to get the egg is to place a piston facing towards it and activate the piston, causing it to drop as an item. If you make the egg fall onto a torch it will be in item form as the egg is affected by gravity, like sand and gravel. It is possible to mine the egg by making a large 30x30x15 cube of blocks with the egg in the very middle. You need to tunnel to the very middle and make the passage out of transparent blocks like doors or fence gates as the egg cannot teleport to these blocks. You can break the egg with your fist and it will drop. This method is not recommended as it will take many stacks of blocks.
