I made this map in two days for the Egg Jam.

Welcome to the Egg Island!
You aim to gather as many eggs from the great chicken as possible. When you have collected enough you may exchange them for even better eggs or use them to give the great chicken better seeds to improve her eggs. When you have made enough of your finest quality of eggs, you may offer them to the altar to free the spirit of chickeness.

When you have done so, feel free to look around in creative mode. I hope you will enjoy this map I've made!
