what temp and humidity incubate duck eggs
1. 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 37.5Â°C (99.5Â°F) and relative humidity at 55% (84.5Â°F on wet bulb thermometer).Set ventilation as recommended by the incubator manufacturer.hen larger numbers of duck eggs are to be hatched, large commercial incubators (setters) and hatchers are normally used. 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.
