How To Make An Incubator Duck Eggs | Home made Egg Incubator Very Easily. If the incubator is not already in operation, start the incubator and allow the temperature and humidity to stabilize a day or two before setting eggs. Set the temperature at 37.5°C (99.5°F) and relative humidity at 55% (84.5°F on wet bulb thermometer). Set ventilation as recommended by the incubator manufacturer. Eggs must be turned, either automatically or by hand, a minimum of 4 times a day. Most automatic turning devices are set to change the position of the eggs hourly. Select eggs to be set by carefully inspecting and candling them at the time they are put in setting trays. Do not set eggs that are cracked, double yolked, misshapen, oversized, undersized or dirty. For best results, set eggs within 1-3 days from the time they were laid. There is an average loss of about 3% hatchability for eggs stored 7 days before setting, and about 10% loss for those stored 14 days. Always set eggs with the small end down, except in the case of small incubators that have no trays. If eggs have been stored in a cooler, take them out of the cooler the night before setting and allow them to warm to room temperature.
