![]() Vents should be opened to their maximum setting by the end of the hatch. As the hatch nears completion gradually lower the temperature and humidity so that by the end of the hatch the temperature is at 36.1☌ (97☏), and the humidity is at 70% (90☏ wet bulb). As the hatch progresses, and eggs begin to pip, increase the humidity to 80% (93☏ wet bulb), and increase ventilation openings by about 50%. At the time of transfer, the temperature of the hatcher should be set at 37.2☌ (99☏) and the humidity set at 65% (88☏ wet bulb). Candle and remove eggs with dead embryos. Check frequently to make sure the incubator is working properly the first day, and continue checking thereafter at least four times a day.Īt about seven days after setting, candle the eggs and remove any eggs that are infertile (clear) or have dead germ (cloudy).Īt 25 days after setting (Pekin eggs), the eggs are transferred to hatching trays, and if eggs are hatched in a separate machine, moved to the hatcher. ![]() On the day of setting, put eggs in incubator, close the doors and allow the incubator to reach operating temperature. 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. Always set eggs with the small end down, except in the case of small incubators that have no trays. 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. For best results, set eggs within 1-3 days from the time they were laid. Do not set eggs that are cracked, double yolked, misshapen, oversized, undersized or dirty. Select eggs to be set by carefully inspecting and candling them at the time they are put in setting trays. Most automatic turning devices are set to change the position of the eggs hourly. Eggs must be turned, either automatically or by hand, a minimum of 4 times a day. Set ventilation as recommended by the incubator manufacturer. Set the temperature at 37.5☌ (99.5☏) and relative humidity at 55% (84.5☏ on wet bulb thermometer). 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. Basic procedures and conditions for hatching duck eggs are as follows. It is not necessary to turn eggs in the hatcher. Eggs are automatically turned while in the setter (usually hourly). Pekin duck eggs are kept in a setter for 25 days and then transferred on the 25th day to a hatcher where they remain until they hatch on the 28th day. When larger numbers of duck eggs are to be hatched, large commercial incubators (setters) and hatchers are normally used. ![]() Eggs from common ducks like Pekins require 28 days to hatch.Įggs from Muscovy ducks hatch in about 35 days after setting. Since duck eggs are larger than chicken eggs, setting trays must be designed to accommodate their larger size. Much of the information available on incubating and hatching chicken eggs can be applied to ducks, as long as the important differences between these two species are taken into account.
