This datapack was created for the warm pig to porse resource pack (but can be used without). That resource pack changes some of the new mob variants to animals from the 2013 April fools update, Minecraft 2.0.

This datapack adds some functionality from the 2013 April fools update, Minecraft 2.0 by making cold and temperate chickens aggressive (Minecraft 2.0 had temperate and blue chickens). And giving cold chickens a 25% chance of being an explosive chicken and a 0.1% chance of exploding each tick.
