How long does it take a chicken egg to hatch using lamp?

Here's why:

* Temperature: While lamps can provide heat, they don't provide the consistent and precise temperature needed for successful incubation. Eggs need a very specific temperature range (around 99.5°F) for proper development.

* Humidity: Incubation requires controlled humidity to prevent the eggs from drying out. A lamp cannot provide this.

* Turning: Eggs need to be turned regularly to ensure even development of the chick. A lamp cannot do this.

Instead of a lamp, you need an incubator. Incubators are specially designed to:

* Maintain the correct temperature.

* Control humidity levels.

* Turn the eggs automatically.

Important Note: Even with an incubator, hatching eggs is a delicate process that requires careful attention and monitoring.
