This incubator is made for all sorts of eggs, such as chicken eggs, duck eggs, goose eggs, turkey eggs, etc. It easily accommodates up to 48 eggs. The LED screen provides information about temperature, humidity, hatching day and egg turning time. This all allows for efficient monitoring and close care. The auto turners automatically turn the eggs around every 2 hours to improve hatch speed. Please note the turners will turn every 2 hours but are not designed to always switch side after turning. If the hatching environment is within proper temperature and humidity level it should not have any negative effect on the eggs.
