The product has never been used; the packaging was damaged during transport. Unopened product, repackaged in our warehouses, in perfect working condition, warranty included. Easy to Use: Our incubator is easy to use, and setup is quick and simple. Regardless of your experience, you can hatch eggs without problems. Best Hatching Rate: Precise temperature control and 360° air circulation ensure even heat distribution and thus the highest possible hatching rate. Automatic Egg Turning: The automatic turner gently turns the eggs like a hen to promote proper development of fertilized eggs. Remember to remove the turntable for the last three days to stop egg turning. (Note: Automatic egg rotation every two hours. The red tray should be removed three days before hatching to avoid injury to the chicks by rolling them.) Pro Dual-Channel Humidity Controller: Two independent humidity trays are connected to external 500ml containers and maintain optimal humidity for 5-7 days per fill. Only 1-2 water bottle changes are required during incubation; without daily water checks, you can enjoy convenient incubation. Built-in Candler and Humidity Display: You don't need an extra candler to monitor egg development. In addition, the control panel displays temperature and humidity for precise control of the egg environment, thereby increasing the hatching rate. 360° Panoramic View: The incubator's 360° transparent lid provides a clear view of the hatching process, allowing you to experience the miracle of life up close. Warning: The vents are closed during incubation. They open when humidity is above 80% and close when it is below.
