How Long Do Duck Eggs Take to Hatch? (Explained for Beginners)

How Long Do Duck Eggs Take to Hatch

Duck eggs bear some resemblance to chicken eggs, but there are several things that distinguish the two. For starters, duck eggs are typically larger than chicken eggs. The shell of a duck egg is also significantly thicker than that of a chicken egg. Read on to find out more about duck eggs, including how long they take to hatch.

The incubation time for duck eggs typically varies by breed, but on average, it takes 28 days to hatch most breeds. One notable exception is the Muscovy duck breed – eggs from this breed can take up to 35 days to hatch.

Do Ducks Sit on Their Eggs Until They Hatch?

When egg laying is complete, a brooding duck will incubate her eggs around the clock. During this period, she will sit on the eggs, only taking brief breaks for water and food.

A mother duck typically sits on her eggs for 20-23 hours a day, taking an average of three breaks, each lasting upto an hour at a time. When she does venture out of her nest, the mother duck covers her eggs with additional nesting material to help keep the eggs warm until she gets back.

What Temperature is Needed to Hatch Duck Eggs?

To hatch duck eggs, set the temperature of the incubator at 37.5°C (99.5°F) and relative humidity at 55% (this is 84.5°F on a wet bulb thermometer).

Within a range of 35 to 40.5°C (84.5 – 104.9°F), there is the possibility of eggs hatching, but the hatch will be reduced, plus there will be an increase in the number of deformed and crippled chicks.

Make sure you set ventilation as recommended by the incubator manufacturer. You’ll need to turn the eggs, whether by hand or automatically, at least 4 times a day.

Do Duck Eggs Hatch at the Same Time?

Although the eggs in a duck’s nest could have been laid several apart, they will all hatch within 24 hours. This is because the incubation period for all the eggs usually starts at the same time.

How to Encourage Duck Eggs to Hatch?

Here are some tips on how to encourage duck eggs to hatch when incubating them:

  • Don’t wash incubating eggs.
  • Store the eggs with the pointy end down to keep the yolk centered in the white.
  • Mist the eggs with warm water (about 100 degrees) to draw out moisture and promote the growth of the air sac which gives the embryo room to grow and expand. A spritz of warm water once a day should be sufficient. This is thought to mimic the wet duck when returning to the nest after finding something to drink and eat and maybe going for a quick swim.

Will Duck Eggs Hatch on Their Own?

Duck eggs are inert when laid. Their incubation period doesn’t start until they’re under the warm body of the mother duck, or in an incubator. Unless the temperatures are freezing, the eggs should keep just fine with a bit of insulation and remain viable during the laying period.

Will Duck Eggs Hatch After Being Refrigerated?

As long as they have been fertilized, you can get refrigerated duck eggs to hatch if you incubate them properly. However, your hatch rate (the number of eggs that successfully hatch) will be much lower.

How Do You Know If a Duck Egg is Alive?

To be able to tell if a duck egg is alive, you’ll want to apply bright light to an egg to see what’s inside. This process is known as candling. Originally, candling was done by using candles in a dark room. Today, you can use a flashlight or a candling light if you prefer.

Hold your preferred lighting device above top of the duck egg to allow the light to shine directly down on it. It is important for the room to be entirely dark so that all the light from the flashlight or candling light illuminates the egg.

Look for any veins within the duck egg, starting at the seventh day of incubation. If you discover clear, distinct veins, it means that the egg is alive. After the 12th day of incubation, you may be able to make out a live embryo.

Do Ducks Leave Their Eggs Unattended?

Female ducks lay up to 13 eggs, producing about one a day. During this period, she may sit on the nest, but incubation doesn’t begin until the last egg has been laid. During this time, she can leave the nest for long periods of time and the eggs will be fine as long as there are no predators nearby.

Once the female has her full clutch, she will sit on the eggs, leaving only briefly to eat and drink, for about 28 days.

Will Duck Eggs Hatch in Water?

Mother ducks usually nest on a patch of dry land that is close to a water body. It is extremely rare for ducks to lay eggs in water. These eggs will need to be brought to dry land (either by the mother duck herself or with help from a human) for them to hatch.

What Temperature Will Kill Duck Eggs?

The optimum temperature for duck eggs is 37.5 °C (99.5°F). When the temperature is above 40.5 °C (104.9°F),  no embryos will survive. Similarly, when the temperature falls below 35°C (95°F), no embryo is likely to survive the hatch. 

Is It Illegal to Hatch Wild Duck Eggs?

Ducks are protected under the Migratory Bird Treaty Act of 1918. This means that it is illegal to take, transport, possess, purchase, or sell them or their parts, such as eggs, feathers, or nests without a permit. Active nests with chicks or eggs may not be purposely touched or destroyed without a permit.

Can a Chicken Hatch a Duck Egg?

A chicken can successfully hatch a duck egg. Certain breeds of chicken tend to go broody and will not lay eggs until the broodiness wears off or they hatch something, in this case, a duck egg.
