Heron Egg

Heron eggs are items that can be thrown to spawn heron chicks. Each egg generates with a spawn chance, which determines the likelihood of a successful hatch when thrown.

Mob Loot
Herons drop a heron egg every 5-10 minutes. This rate can be changed via the mod config.

Analysis
Heron eggs have a chance of being obtained by analysing a mystery egg in an egg analyser.

Combat
Just like chicken eggs, players are able to throw heron eggs to deal knockback to mobs, but no damage is dealt, similar to a snowball. Likewise, throwing heron eggs at neutral mobs provokes them. Heron eggs can also be fired from dispensers and are affected by gravity.

Spawning Chicks
Each heron egg generates with a spawn chance. The spawn chance is slightly higher when discovered via an egg analyser than when laid by a parent heron. An egg spawned in creative mode will have a 30% spawn chance. The spawn chance can be increased up to 100% by placing the egg in an incubator or by directly combining the egg with blaze powder in a crafting grid. Each level of incubation increases the spawn chance by 10% for each powder used.

When thrown by a dispenser or by pressing the use button, the spawn chance determines whether it should spawn a heron chick. If the spawn chance is at 100%, a chick will always be spawned. If a hatch is successful, there is a 1⁄32 chance of spawning three additional chicks.

If the egg has a variant tag, the chick spawned will be of that variant, otherwise the variant is randomised. An egg spawned in creative mode will have an unknown variant. Eggs are only stackable if the spawn chance and variant are the same.

Crafting Ingredient
Heron eggs are registered in the forge dictionary using the 'forge:eggs' tag. They are compatible with any egg recipe.
