Why does the incubator used by a silkworm farmer need to be so large?

The incubator used by a silkworm farmer needs to be large to accommodate the significant number of silkworm eggs and larvae that are raised simultaneously. A larger space allows for adequate airflow, temperature control, and humidity regulation, which are crucial for the healthy development of the silkworms. Additionally, it provides enough room for proper feeding and the management of silk production, ensuring optimal growth and yield.
