Many people want to help the ducklings hatch. Losing significantly more or less than this reduces hatchability. Ideally a duck egg loses about 13% of its weight between the time it is laid and day 25 of incubation. One consequence is it changes the membrane of the egg so a greater percentage of moisture is lost during incubation. The actual consequences of spraying is interesting. The incubator should be able to warm up in about the same amount of time it took to cool the eggs.
Then you can spray the eggs with room temperature water and return them to the incubator. If it feels warm it needs more cooling, if it feels neutral you are done cooling, if it feels cool you have cooled too long. If you do not have a way to accurately read the temperature, hold the egg to your eyelid. If you have an infrared temperature gun, cool the eggs until the shell surface reaches 86 degrees. Open the incubator or remove the eggs so they cool. Sometimes a regime of cooling and spraying duck and goose eggs results in better hatchability. If they are raised at all, it is important that the large end with the air sac be up. Most eggs are incubated on their sides in small incubators. When you turn the eggs, the line should either be on the top or the bottom of the egg. This is important so you do not leave the eggs in the same position each night which is the longest period of time they go without turning each day. If you do not have an automatic turner, it is important you turn the eggs an odd number of times each day. Turning is most critical the first week of incubation. Without a fan, the warm air rises and you will get a false reading if you place your thermometer on top of the eggs. If your incubator does not have a fan, measure the temperature half way up the side of the egg. You can adjust the humidity by increasing the amount of water in the incubator or reducing ventilation. If the air is very humid, less evaporates which cools the thermometer less and a higher temperature is recorded. If the air is very dry, much water evaporates from the cloth, cooling the thermometer. As the water evaporates from the cloth, the thermometer is cooled. Place the other end in a container of water and put it all in the incubator. If you wish to measure the humidity in your incubator via wet bulb, you can make your own wet bulb by placing the end of a short, hollow shoestring over the end of a thermometer. This is only for estimating purposes, you should determine your average air pressure if you are dealing in relative humidity.
You can probably look up your air pressure on your local television station's web site or use an average of about 30 inches mercury. The only additional factor that relative humidity requires is air pressure. If you go to you can convert from one to the other. There are two common methods of measuring humidity: wet bulb and relative humidity.
We do not sell goose hatching eggs as they are difficult to ship and do not hatch as well as duck eggs.įollowing are the conditions recommended for incubation and hatching: The minimum charge for the eggs is $50.00. In our large commercial incubators, we normally hatch 70-75% of all eggs set. That is entirely dependent on the incubator. We cannot guarantee that the fertile eggs will hatch. You must candle the eggs within 14 days of the ship date and notify us at that time if the fertility is less than 80%. We will guarantee that at least 80% of the eggs you purchase are fertile. Once you obtain an incubator, it is important you follow all directions supplied with the machine. You will have two decisions to make in your purchase:ġ) Do you want a fan? For the smallest incubators, this is not important.Ģ) Do you want an automatic turner? If you expect to use the machine many times, this would be advisable. Incubators are made to handle anywhere from 2-50,000 eggs.įor smaller sized incubators, contact one of the following: When incubating eggs, it is important you use an accurate incubator. If you candle your eggs, you can compare their progress with the pictures we have of duck eggs for every day of incubation in our Egg Candling Series.įor more information on single stage incubation, which is the procedure we use to incubate all of our eggs, please read our article, Single Stage Incubation. Besides the information below, there is valuable incubation information elsewhere on our website. The incubation and hatching of duck and goose eggs is not a difficult experience and can be very rewarding.
