Vulture Egg

Vulture eggs were items that could be thrown to spawn vulture chicks. Each egg generated with a spawn chance, which determined the likelihood of a successful hatch when thrown.

Mob loot
Vultures dropped a vulture egg every 5-10 minutes. This rate could be changed via the mod config. Vultures only lay eggs when on the ground, so would not do so while circling.

Analysis
Vulture eggs had a chance of being obtained by analysing a mystery egg in an egg analyser.

Combat
Just like chicken eggs, players were able to throw vulture eggs to deal knockback to mobs, but no damage was dealt, similar to a snowball. Likewise, throwing vulture eggs at neutral mobs would provoke them. Vulture eggs could also be fired from dispensers and were affected by gravity.

Spawning Chicks
Each vulture egg generated with a spawn chance. The spawn chance was slightly higher when discovered via an egg analyser than when laid by a parent vulture. An egg spawned in creative mode would have a 30% spawn chance. The spawn chance could 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 increased the spawn chance by 10% for each powder used.

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

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

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