The Mighty Ender Chicken is an alternative boss to the Ender Dragon. It’s a massive beast and very difficult to kill. All you need is 8 obsidian blocks and a diamond block to spawn it by dropping an egg on the platform.

The chicken will then begin to spawn into a giant egg made of obsidian.

It’ll take some time to hatch from that egg then get ready because this chicken will leave a path of destruction wherever it goes.

And this mod also has an even harder boss to defeat, the Chaos Chicken. You can spawn it the same way only you’ll need to drop a dragon egg on the platform instead.

This one looks similar but wreaks significantly more havoc on your world and takes longer to hatch from its protective shell leaving you incapable of damaging it!

This mod requires an additional API found here.
