Development of a Still-Air Incubator with a Non-Thermostatic Control
Abstract
The study reported is part of a continuing effort at improving locally fabricated incubators. The incubator developed uses electric bulbs as the heat source and has an uninterruptible power supply which is cheap to maintain, compared to a generating set. A resistance-varying device was used to control the temperature manually while the humidity was varied by varying the sizes of water pans placed on the floor of the incubator. The eggs were turned three times daily for the first eighteen days with a semi-automated device. The temperature and humidity were successfully controlled. The percent hatchability of the incubator was 62%, while the energy consumption was 3.96 kWh per chick.
