Why do the incubator used by the silk farmers not need to be large?

The incubator used by silk farmers does not need to be large because it is designed to house a limited number of silk eggs, which require specific conditions for optimal hatching. The primary focus is on maintaining appropriate temperature and humidity levels rather than accommodating a vast amount of space. Additionally, the silk production process is often efficient, allowing for smaller, controlled environments that can be easily managed. This maximizes resource use and creates ideal conditions for the eggs to develop.
