Silk Harvest

Silk Harvest

In vanilla Minecraft, spawn eggs are creative-only items. This mod allows you to obtain them in survival.

Core Mechanic

When a mob is killed by a player using a Silk Touch enchanted item, there's a chance it will drop its vanilla spawn egg. The drop rate depends on the mob type among other factors.

Features

Tiered Drop Chances

Category	Mobs	Base Chance	Special Requirements
Common Passive	Cow, Pig, Sheep, Chicken, Rabbit, Cod, Salmon, Tropical Fish	70%	Baby penalty: -20%
Neutral/Hostile	Zombie, Skeleton, Spider, Enderman, Drowned, Stray, Husk, Wolf, Bee	30%	No spawner/tamed drops
Rare/Utility	Slime, Witch, Guardian, Blaze, Ghast, Endermite, Shulker	10%	Requires Looting II+
Bosses	Ender Dragon, Wither	0%	Excluded for balance

Balancing Mechanics

• Durability Tax: Your Silk Touch tool takes +10 durability damage when an egg drops
• Looting Bonus: Each level of Looting adds +10% to the drop chance
• Spawner Protection: Mobs from spawners never drop eggs
• Tamed Protection: Your pets are safe - tamed mobs won't drop eggs
• Advancement Gating: Certain rare mobs require progression advancements:
  • Enderman eggs require "Free the End"
  • Blaze eggs require "Into Fire"
  • Guardian eggs require "The Deep End"
