Simply Spawners adds features to better utilize spawners in a survival game.

Spawner Fragment: The spawner fragment is obtained from spawners broken with a pickaxe enchanted with fortune 1-3. Fortune 3 guarantees 4 fragments to drop.

Empty Spawner: The empty spawner when right clicked with a mob egg is converted to an active spawner set to the eggs mob spawn. This can only be mined with a silk touch tool.

Empty Egg: The empty egg is used to convert an active spawner (vanilla) to an empty spawner. This can be crafted with a chorus fruit and a vanilla mob spawn egg. Modded spawn eggs will not work for this recipe (refer to the technical stuff section for more information).

The enchantment "Eggification" can be found in nether fortresses, near portal frames, and in bastions. The enchantment when applied to a weapon adds a small chance for mob spawn eggs to drop when a mob is killed. This chance is increased when combined with looting on the weapon.

Technical Stuff:

The enchantment mimics the "middle click" function to get a mob egg so this should work with modded entities. Spawners get the entity data from the spawn egg item so any mob egg from a modded entity should be able to be added to a spawner (This is vanilla function of spawners). The only limited mod compatibility is with the crafting recipe for the empty egg, this item is crafted using a mob egg and this is done using a forge tag list which all of the vanilla mob eggs have been manually added too. A modded mob egg will have to be added to this list to be made compatible, the forge tag is spawn_eggs.

If any other compatibility issues or bugs pop up let me know and I will look into it when I have the time.
