How to Build a Homemade Egg Incubator Using a Water Bottle

### ✅ Step 2: Set Up the Heat Source

* Attach the **light bulb** to a lamp holder or socket.
* Carefully position the bulb **inside the bottle** without it touching the plastic.
* Cut a small hole in the side of the bottle to pass the lamp’s wire through.

> ⚠️ **Safety Tip:** Use low-wattage bulbs to prevent overheating or melting the plastic. Avoid LEDs — they don’t produce enough heat.

### ✅ Step 3: Create the Egg Chamber

* Place a layer of **cotton, sponge, or soft cloth** at the bottom to cushion the eggs.
* Set the **small bowl of water** inside to maintain humidity.
* Gently place your **fertile eggs** inside, spacing them evenly.

### ✅ Step 4: Regulate Temperature & Humidity

* Insert a **thermometer** inside the bottle to monitor the temperature.
* Ideal incubation temperature: **99–102°F (37.5–39°C)**
* Humidity should be around **50–55%** for the first 18 days, then **65–70%** for the final 3 days.

> 🔄 Turn the eggs **3–5 times a day** to mimic a mother hen’s behavior. Stop turning on day 18.

## 🛠️ Tips for Success

* Keep the incubator in a **stable, warm room**, away from windows or drafts.
