Chicken Nugget allows you to craft chickens similar to crafting ingots by combining 9 nuggets in a crafting table. As soon as you finish the recipe, out pops a chicken!
Nuggets can be acquired by simply killing chickens so you can make more chickens from dead chickens in a sense. You can also cook the nuggets to make edible chicken nuggets, although you can’t make a full chicken after you’ve cooked the nuggets.
And you can even cut off a chicken’s head and it’ll run around for a bit before eventually dying.
The head can be stored or even worn and you can truly become the chicken.
