A fully automatic egg incubator is a machine that is designed to incubate eggs without any intervention from the operator. These incubators are equipped with sensors, controllers, and mechanisms that regulate temperature, humidity, ventilation, and egg turning automatically.

Here are some features that a fully automatic egg incubator may have:

1. Digital control panel: This panel allows the operator to set and adjust the temperature, humidity, and turning frequency of the eggs. It also displays information such as the temperature and humidity inside the incubator.
2. Automatic egg turning: An egg incubator that is fully automatic turns the eggs at regular intervals without any input from the operator. This helps to ensure that the developing embryos receive equal exposure to heat and oxygen.
3. Fan-forced ventilation: A fully automatic egg incubator has a fan that circulates air inside the incubator, helping to maintain a consistent temperature and humidity throughout the incubator.
4. Egg candling: Some incubators has an automatic egg candling feature, which allows the operator to view the inside of the egg to check for fertility or developmental issues.
5. Automatic alarms: A fully automatic egg incubator has alarms that notify the operator if the temperature or humidity levels are outside of the desired range.
6. Capacity: Automatic egg incubators range in size and capacity. Some can hold as few as a dozen eggs, while others can hold several hundred.

Overall, a fully automatic egg incubator makes the incubation process easier and more efficient for poultry farmers by automating many of the tasks involved in incubating eggs.
