No; you just need a minecraft version Beta 1.9 or above.
Harvesting them can be tricky, so to get one:
-
Defeat the Enderdragon.
-
He will create a return portal under his point of death.
-
Walk up to the egg on top of it, then:
-
Push it with a piston.
-
Punch it so that it teleports, then smack it out of the air on its way down.
-
Start punching an adjacent block, then, before it breaks, move your cursor to the egg.
