# Egg-Laying Mechanism

When your animal has an **active Nest NFT** in its <mark style="color:purple;">**Token Bound Account (TBA)**</mark> —meaning you've assigned a Nest for your animal to use—only then will it have a chance to lay eggs.

Simply put:

* **With a Nest**, your animal has a chance to lay eggs, and you will receive **a free egg**.
* **Without a Nest**, your animal **will NOT** lay eggs.

## **When Can Your Animals Lay Eggs?**&#x20;

* Animals <mark style="color:yellow;">**can lay eggs when they reach the stage 3 (or level 3) of their live circle.**</mark>&#x20;
* However, this only happens **if the Nest NFT is active inside the TBA** (meaning the Nest NFT has been assigned to that animal NFT).&#x20;

## **Conditions for Laying Eggs?**

For the animal to lay eggs, it must meet **all the conditions** below:

* The **status must be "Full"** (meaning it has been fed).
* The animal **must have a Nest NFT** assigned.

The **egg-laying probability depends on the animal's rarity**:

* **Common** → 10% chance
* **Rare** → 20% chance
* **Super Rare** → 40% chance

<mark style="background-color:$info;">**Without a Nest NFT, the animal will never lay egg, regardless of the status.**</mark>&#x20;

## **Types of Eggs & Hatch Rates**

There are **two types of eggs**: **White Eggs** and **Golden Eggs**.&#x20;

### **White Egg**

* White Egg is laid by **Common type** and **Rare type** animals.
* Hatch rates:
  * **87.5%** → Hatches into a **Common** type.
  * **10%** → Hatches into a **Rare** type.
  * **2.5%** → Hatches into a **Super Rare** type.

### **Golden Egg**

* **Only Super Rare type Animals** can lay **Golden Eggs**.
* Hatch rate: Golden Egg has a **100% chance** to hatch into a **Super Rare** type animal.&#x20;

## **Key Takeaways**

* **Having a Nest NFT is essential**—without it, animals won’t lay eggs.
* **Egg-laying is not guaranteed**; the chance depends on the animal's rarity.
* **Higher rarity animals have a better chance of laying eggs** and hatching stronger offspring.

By managing your **Nest NFTs and feeding your animals properly**, you can maximize your chances of **breeding rare and valuable animals** in the game!
