Humidity of incubator for chicken eggs9/10/2023 ![]() ![]() Hatching takes a lot of energy and it will be a slow process usually taking a full 24 hours or longer for all ducklings to complete the hatch. The day before the hatch you should prepare their brooder. You also want to increase the humidity to around 65-70%. The ducklings are nearly fully developed and they will position themselves inside the egg to prepare for hatching. On day 26 of the incubation period, you should stop turning the eggs by hand or turn off and remove eggs from the automatic turner. Any eggs that appear clear with no developing embryo should be removed from the incubator. The embryo should appear as a tiny “spider” with veins radiating from the dark spot. Add water to the humidity reservoir as needed to maintain the necessary humidity level.Īt around day 10, you may want to candle the eggs to check for a developing embryo. Many people who hatch duck eggs report better hatch rates when turning the eggs by hand.ĭuring this period, you will also monitor the temperature and humidity. Step 4: Incubating, Days 1-25ĭuring the first 25 days of incubating, you will need to hand turn the eggs at least once every 8 hours if not using an automatic turner. Even if you have an automatic turner in your incubator, marking helps you ensure that the turner is working properly. Marking the shell helps you visualize that they have been turned properly and frequently. During the incubation period, you will rotate the eggs. When you are ready to set the eggs into the incubator, mark an X on one side of the shell using a soft pencil, and an O on the other end. This helps prevent the embryo from sticking to the shell membrane. Rotate which end is propped up approximately every 12 hours. If you are holding the eggs for longer than 24 hours before beginning incubation, prop one end of the carton up a few inches. ![]() Place the eggs into a cardboard egg carton with the pointed end down and set in a quiet spot in the same room as the incubator. If you are not ready to begin the incubation period on the day that your eggs arrive, you may “hold” your shipped eggs for up to 10 days from the ship date.īefore you handle hatching eggs, always wash your hands thoroughly to prevent bacteria from entering through the porous eggshell. Setting cold eggs in a warm and humid incubator will cause the eggs to crack and the embryos will die. If your duck hatching eggs have been shipped in the mail, allow at least 24 hours rest to let the yolks settle and for the eggs to reach room temperature. If this happens, the duckling becomes stuck inside the shell and will likely perish. Without enough humidity, ducklings tend to become “shrink-wrapped” when the shell membranes dry up and contract around the duckling, restricting its movement within the shell. The correct humidity levels during incubating and hatching are much more important for waterfowl than they are for chickens. Then once the ducklings begin to pip in the final 24 hours, humidity can be allowed to increase even more to 80% (92 wet-bulb). Then as the ducklings prepare to hatch, the humidity should be increased to 65-70% (88-90 wet-bulb).
