Automatic Incubator: This unit features a builtin control system that can simulate natural incubation conditions. It automatically flips the eggs every 120 minutes with 360degree allround rotation for no dead angle, and provides automatic temperature control, automatic water replenishment, and automatic lighting, making it smart and easy to use. Adjustable Egg Tray: The distance between egg trays can be adjusted to fit eggs of different sizes, ensuring eggs do not miss or get stuck when spacing is too large, and do not collide when spacing is too small. Automatic Lighting for Breeding Eggs: Chicken embryos are automatically illuminated for the first time on day 7 to observe development, and again on day 14 to clearly see the progress of the whole embryo. Easy to Use: The fully automatic incubator features a smart system that is easy to operate for both professionals and beginners, allowing the entire incubation process to be managed with this incubator. Practical use scenarios: Home hobbyists incubating backyard eggs; small farms or hatcheries needing to hatch eggs of different sizes by adjusting tray spacing; classrooms or science projects to observe embryo development with day 7 and day 14 lighting.
