Then you can spray the eggs with room temperature water and return them to the incubator. The incubator should be able to warm up in about the same amount of time it took to cool the eggs. Do not spray and cool after day The actual consequences of spraying is interesting. One consequence is it changes the membrane of the egg so a greater percentage of moisture is lost during incubation. Losing significantly more or less than this reduces hatchability.
Many people want to help the ducklings hatch. It is best to allow them to do the hatching themselves. The only time you want to help them is when they make a hole and then cannot progress because they get stuck in that spot. If an actual hole is made and you can see the duckling, but no progress is made for 12 hours, you can gingerly help the duckling. If blood appears where you break pieces of the shell off, stop and wait several hours.
If the duckling gets stuck after it has started to break a circle around the egg, it can usually be helped without a problem. But if they are progressing on their own, do not help them. It is important that the incubator not get too warm or too cold as it will affect the eggs. Several hours of too high a temperature is more dangerous than several hours of too cool a temperature.
If your electricity goes out or you must move your incubator, do not worry but watch that it does not become too warm. If the temperature starts to rise, open the lid to allow more ventilation. The length of incubation time varies. For Mallards it is about For Runners it is All others are about 28 days. If your eggs are old or the incubator is cool, incubation takes longer. If it is too warm, incubation will be completed sooner. Do not attempt to control the length of time for incubation by increasing or lowering the temperature from the ideal.
This will lower the hatchability of the eggs. Eggs can be held for a week before incubation without a problem. Being very light and covered in down they usually come to no harm during the fall. If the landing area is very hard and there is cause for concern, placing something soft like straw or a blanket underneath will cushion the fall.
Next they will have a long and potentially hazardous walk before they can reach water. Young ducklings can feed themselves as soon as they reach water, but must learn what is edible. They depend on their mother for warmth for a few days. She broods them regularly, particularly at night, as they easily chill in cold weather. The down of the ducklings is not naturally waterproof.
They get the waterproofing for their down from their mother. She also protects her ducklings from attacks by other mallards. Ducks do not tolerate stray ducklings close to their own brood, and females kill small strange young they encounter. Ducklings take days to fledge fly and become independent. They are able to breed when they are a year old. Martin Harper Blog. How nature can help protect our homes Following the floods this winter, watch how one area is using nature as a natural protector.

Then, in a span of 24 hours, all the ducklings will hatch from their eggs, using a small sharp bump on their bills called an "egg tooth.
Once all the ducklings have hatched, the mother duck typically spends one more night on the nest, helping to warm and dry the newly hatched brood. The next day, she will begin to take the ducklings out to find food and forage, as they follow her closely. Many domestic ducks have no experience with brooding or incubating, and tend to neglect their nests or ducklings. When this occurs, fertile eggs are usually incubated by a broody hen, if one is available, or by artificial incubation.
The amount of time required to hatch the eggs is the same, however hens cannot typically keep an entire clutch of duck eggs warm, due to the large size of the eggs in comparison to her body.
