Blue Jay Egg

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

Mob Loot
Blue jays drop a blue jay egg every 5-10 minutes. This rate can be changed via the mod config.

Analysis
Blue jay 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 blue jay eggs to deal knockback to mobs, but no damage is dealt, similar to a snowball. Likewise, throwing blue jay eggs at neutral mobs provokes them. Blue jay eggs can also be fired from dispensers and are affected by gravity.

Spawning Chicks
Each blue jay egg generates with a spawn chance. The spawn chance is slightly higher when discovered via an egg analyser than when laid by a parent blue jay. 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 blue jay 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
Blue jay eggs are registered in the forge dictionary using the 'forge:eggs' tag. They are compatible with any egg recipe.
