🎮 Player & Survival Gameplay Workflow
- Egg Collection vs. Breeding:
- Chickens laying regular eggs every 5–10 minutes produce Unfertilized Eggs (safe for baking cakes and pies without accidental chick explosions).
- Autonomous Chicken Mating:
- When adult chickens mate autonomously in grassy pastures or near seed crops, they roll a 50/50 chance to either hatch an immediate baby chick or drop a Fertilized Egg entity item.
- Manual Player Incubation:
- Right-clicking (throwing) a Fertilized Egg provides a guaranteed 100% hatch rate for a healthy chick.
- Automated Hatcheries (Dispensers):
- Loading Fertilized Eggs into redstone Dispensers fires eggs with a 75% hatch rate, allowing high-throughput automated farm designs.
🧮 Mathematical Probabilities & Dispersion Matrix
1. Autonomous Mating Distribution
When two chickens complete a breeding cycle:
$$R = \text{random.nextFloat}()$$
$$\text{Outcome} = \begin{cases} \text{Instant Baby Chick} & \text{if } R < 0.50 \ \text{Fertilized Egg Item Drop} & \text{if } R \ge 0.50 \end{cases}$$
2. Egg Hatch Comparison Table
| Egg Type | Delivery Method | Hatch Chance | Offspring Quality |
|---|---|---|---|
| Fertilized Egg | Player Throw | 100% (1/1) | Inherits parent scale & genetics |
| Fertilized Egg | Dispenser Ejection | 75% (3/4) | Inherits parent scale & genetics |
| Regular Egg | Player Throw / Dispenser | 1.56% (1/64) | Random baseline vanilla stats |

Mixin Interception on Egg Impact
ThrownEggMixin intercepts onHitEntity and onHitBlock:
java
// Intercept thrown egg impact to check for Fertilized Egg CustomData
@Inject(method = "onHit", at = @At("HEAD"), cancellable = true)
private void naturalreproduction$onEggImpact(HitResult hitResult, CallbackInfo ci) {
if (ChickenEggHelper.isFertilizedEgg(this)) {
ChickenEggHelper.handleFertilizedEggImpact(this, this.level(), hitResult);
ci.cancel();
}
