Ingredients (Materials Needed)
- 1 large clean plastic water bottle (5–10 liters works well)
- 1 small low-wattage light bulb (15–25 watts) OR a small heating pad
- A lamp holder or socket (if using a bulb)
- Aluminum foil or reflective tape
- Small computer fan or battery-operated fan (optional but helps air circulation)
- Thermometer and hygrometer (to monitor temperature and humidity)
- Some tape and scissors
- Small bowl or sponge (for humidity)
- Eggs for incubation
Instructions
- Prepare the Bottle:
- Rinse the water bottle thoroughly and dry it.
- Cut a rectangular window on one side large enough to easily place the eggs inside and adjust things if needed. Leave a hinge so you can tape it closed again.
- Install the Heat Source:
- If using a bulb, carefully install the socket inside the bottle and secure the bulb so it does not touch the eggs or plastic.
- If using a small heating pad, tape it safely along the inside wall of the bottle.
- Add Reflection:
- Line the inside of the bottle with aluminum foil to help retain and reflect heat evenly. Be sure not to cover any vents you make.
- Control Humidity:
- Place a small bowl of water or a damp sponge inside the incubator to maintain humidity. Monitor with the hygrometer.
- Ventilation:
- Make a few small holes on the bottle to allow air exchange. If you have a small fan, position it to circulate air gently inside.
- Monitor Temperature:
- Place the thermometer inside at egg level. Aim for a stable temperature around 37.5°C (99.5°F) and humidity around 50–60% (higher during hatching).
- Add the Eggs:
- Gently place the eggs inside. Keep them on their sides and turn them slightly 3–5 times a day to mimic how a hen would move them.
- Check Daily:
- Check temperature and humidity at least twice daily. Adjust your bulb wattage or opening for ventilation to maintain correct levels.
- Wait and Hatch:
- For chicken eggs, incubation usually takes 21 days. Increase humidity to about 65–70% in the last few days to help chicks hatch easily.
Safety Tip: Always supervise the heat source and incubator—homemade incubators can be a fire hazard if left unchecked.
