# Eggs

Eggs are essential items in Jurassic Saga's genetic engineering system, serving as the foundation for creating prehistoric creatures.  
Different egg types are required for different species, and understanding which egg to use is crucial for successful creature revival.

---

## Egg Types

### Chicken Egg
- **Size Category**: Small
- **Used For**: Small reptiles and birds
- **Obtain**: Naturally laid by chickens

---

- **Obtain**: Naturally laid by frogs
- **Examples**: Amphibian species

---

### Ostrich Egg
- **Size Category**: Large

---

### Fish Egg

---

### Basilisk Egg

---

## Gestated Embryo

<Callout variant="warning">
    The Gestated Embryo is currently only obtainable in Creative mode, as the chamber required to craft it is not yet
    obtainable in Survival.
</Callout>

The Gestated Embryo is not an egg, but functions similarly as the revival vessel for certain creatures that do not hatch from eggs.
- **Used For**: Palaeoloxodon and potentially other mammals
- **Obtain**: Crafted using a dedicated gestation chamber (not yet obtainable in Survival)

---

## Egg Processing

### Cleaning Eggs

Before fertilization, eggs must be cleaned:
1. Place the egg in a crafting table with a [**Syringe (Clean)**]($content/items/syringe)
2. **Output**: Unfertilized Egg
3. The syringe becomes dirty after use

### Fertilizing Eggs

Once cleaned, eggs can be fertilized with DNA:
1. Place **DNA (100% quality)** + **Unfertilized Egg** + **Syringe (Clean)** in a crafting table
2. **Output**: Fertilized Egg (species-specific)
3. The syringe becomes dirty after use

For detailed instructions, see [**Creating an Egg**]($guides/creating_an_egg).

---

## Usage

### In Creature Creation

Eggs are the final vessel for DNA before incubation:
1. Extract DNA from fossils using the [**Genetic Analyzer**]($content/machines/genetic_analyzer)
2. Refine DNA to 100% using the [**DNA Modifier**]($content/machines/dna_modifier)
3. Clean the appropriate egg type with a syringe
4. Fertilize the egg with your DNA
5. Place the fertilized egg in an [**Incubator**]($content/machines/incubator)
6. Wait for the egg to hatch

### Matching DNA to Eggs

Each creature's DNA requires a specific egg type:
- Check the creature's page to see which egg type is required
- Using the wrong egg type will not work
- The egg type is based on the creature's size and classification

---

## Obtaining Eggs

### Natural Sources

Most eggs are obtained from living creatures in your world:
- **Chicken Eggs**: Naturally laid by vanilla chickens
- **Frog Eggs**: Find frogs in swamp biomes
- **Spider Eggs**: Rarely dropped by spiders
- **Alligator Eggs**: Obtain from in-game alligators
- **Ostrich Eggs**: Obtain from in-game ostriches
- **Fish Eggs**: Obtain from specific fish species
- **Basilisk Eggs**: Obtain from in-game basilisks

### Farming Tips

- Build dedicated farms for egg-producing creatures
- Alligators, ostriches, and basilisks are creatures added by Jurassic Saga
- Keep multiple animals of each type for consistent egg production
- Some eggs may be rarer than others depending on creature spawn rates

## Tips

- Always check a creature's wiki page to confirm which egg type it requires
- Stock up on common egg types like Chicken, Alligator, and Ostrich Eggs for frequent use
- Build farms for Jurassic Saga creatures (alligators, ostriches, basilisks) to ensure a steady egg supply
- Keep cleaned eggs separate from raw eggs to avoid confusion
- Ostrich Eggs are needed for the largest creatures, so prioritize ostrich farming

---

## Trivia

- The egg system in Jurassic Saga adds realism to the genetic engineering process, requiring appropriate vessels for different creature sizes
- The variety of egg types reflects the biological diversity of prehistoric life
- Alligator Eggs are the most versatile, used for many medium-sized dinosaurs
- The egg cleaning and fertilization process mirrors real-world laboratory procedures
- In the Jurassic Park franchise, eggs were artificially created in laboratories, but Jurassic Saga uses a hybrid approach combining natural eggs with genetic engineering
