挪威采购需求：购买孵化器，鸭子孵化，鸡蛋孵化器温度，hhd 12 枚蛋孵化器，孵化器孵化机，鸡蛋自然孵化

I'm reaching out to get more details about the ventilation design on the machine we're considering for purchase. Specifically, I'd like to know where the ventilation holes are located. Understanding their placement is crucial for us to ensure proper airflow and cooling during operation. Additionally, if you could provide insights on how the ventilation features contribute to the overall performance of the machine, that would be super helpful. It's important for us to assess this aspect to make an informed decision. Thanks for your assistance!
