Zombie Healing And Breeding

You can breed two zombies, similar to most passive mobs, by feeding them each rotten flesh.this can be useful for early game xp farms. this can also add more levels to your zombie fights, because when fighting a horde, zombies will pick up the rotten flesh of other dead zombies and eat it similar to pandas to heal up during a fight.

I think this is a great idea, because it make zombies a more complex mob, and gives a real use to rotten flesh, besides just trading.
