If the parents are the same breed, your eggs have higher chances of remaining viable and hatching. If for example, another species of bird mates with your duck, your duck might lay eggs, but the eggs will not be fertile and therefore will not hatch.
Before inserting the eggs into an incubator, check the state of the eggs. Eggs that are deformed, have two yolks, are too large or small have lower chances of developing, so you should carefully examine the eggs.
You may not incubate your duck eggs immediately after their mother lays them, but the temperature and humidity in the place you keep them matter a lot. Storing them at a lower temperature can damage the eggs.
If you store the eggs at a higher temperature, the development of the embryo can start but it will die off because the temperature is not high enough to sustain them. The best way to monitor the progress of your eggs is by candling them. To candle your eggs, lay them on a source of bright light.
You may get any of the following observations:. You should candle the eggs every week. Another way to know if your duck eggs are growing is by measuring their weight. The weight of the eggs should be reduced because air will gradually replace the water in the egg. Some ducks are bad mothers, others are good. One reason your duck does not sit on her eggs quickly is that she might be expecting other eggs. Ducks do not lay all their eggs at once, but they do start the incubation period of every egg at the same time.
If you give your duck time, she will sit on the eggs if they are fertile. If, however, you cannot wait, you should use an incubator. Ducks can tell if an egg is still viable or not. A mother duck will not abandon an unhatched viable egg. If the egg is not viable, however, a mother duck will leave the nest with the hatched ducklings.
Some homesteaders leave the eggs with their mother. Others incubate the eggs by themselves. You should decide what you want and what works best for you. You also need to consider how many eggs a duck can incubate at a time. Muscovy ducks, for example, can incubate eggs at a time. As a general rule , you don't want to wash your hatching eggs and if you're collecting your own eggs, you can store them for days in a cool, dry location with the pointy end facing down while you're collecting all the eggs you want to hatch.
I gently cleaned off all the dirt and shavings that I could with a dry paper towel and then let the eggs sit out at room temperature for a few hours in an egg carton, pointy end down, on the kitchen counter, just to let the yolk recenter itself a bit. It's important to wash your hands before and after handling the eggs. The egg shells are porous and bacteria can easily be introduced through the shell which will kill the baby duckling.
Also careful handling is important so the eggs don't get dropped. While I was waiting for the eggs to settle and adjust to room temperature, I candled each one looking for tiny hairline cracks that might have occurred during shipping, but they all looked great. Candling merely means shining a directly beam of light through the eggshell of a developing egg to look for signs of the embryo growing inside the egg.
Originally a candle was used to shine the light, hence the term "candling". Before you set your hatching eggs, you should also candle them to look for cracks which could cause the egg to become contaminated and not hatch. Once the incubation period has started, you can also check for a blood ring which indicates bacteria has gotten into the egg and it must be discarded.
I generally like to candle my hatching eggs just before I set them, on day 4, day 7, day 14 and day Eggs that aren't advancing through the development process or are contaminated can be discarded throughout the incubation period. I find it easiest to candle while its dark outside and just leave the lights off in the room.
Then, leaving the eggs in the incubator, just shine the light through each one. Had there been any tiny cracks, the beeswax bar can be slightly softened and applied to the crack to seal it from air and bacteria without harm to the embryo. If you accidentally crack an egg during the incubation period, you can also try sealing it with the beeswax. I just use a regular Mini Maglite flashlight to candle the eggs but Brinsea sells several different types of egg candlers that you can use also.
If you're hatching eggs under a broody hen or duck, it's important to set them all at the same time and then remove any eggs that others lay in the nest after the incubation period has started.
It's easier to keep track of which are the original eggs if you mark them. You can use a pencil or a Sharpie permanent marker. A Sharpie works better under a hen - the pencil can tend to get rubbed off. If you're using an incubator,the pencil works great.
I wrote a number on each egg to be able to tell them apart. The number also serves as a reference for the daily turning. I know that every other day the number will be facing up when I'm done turning.
I am using the Brinsea Mini Advance incubator which will hold all six eggs, although I will have to manually turn them because they are too large for the automatic turning tray to accommodate all six. Some incubators have turning trays, in which case you don't have to worry about marking or turning the eggs. Duck eggs need to be kept at temperatures between When the incubator was up to temperature and the eggs had been sitting out for about 6 hours, I set them in the incubator with the pointy end facing outwards and the numbers facing up.
After setting the eggs, I filled up one side of the reservoir with water, according to the incubator instructions. Throughout the incubation period, I will monitor the reservoir to be sure it stays filled, topping it off when necessary.
This increases the humidity in the incubator and keeps the membrane inside the shell from drying out and literally shrink wrapping the ducklings. Since I'm not using the turning tray, I put a piece of rubber shelf liner I cut to fit the base of the incubator.
The shelf liner prevents the eggs from rolling around and also will provide a nice surface for the ducklings feet to grip when they hatch. If you do use the turning tray, just wait to put the shelf liner in when you remove the turning tray for the lockdown period.
Here's the "nursery" I set up with the incubator, my countdown calendar, a pitcher of water to refill the reservoir and my Maglite. I have the nursery set up in a spare room that doesn't get any traffic, is safe from our dog and cat, and stays a fairly consistent temperature. I always make sure the incubator is set up away from a sunny window to avoid accidental overheating.
According to my calendar, on June 28th we should have some baby ducklings "eggscape" their egg prisons and enter the world! I turned the eggs this morning at 6am when I woke up - each egg is turned a degree turn so the numbers are now on the bottom. I like to turn my hatching eggs 5 times a day. But this is one of those situations where more is better.
Small-bodied waterfowl are limited by their ability to store significant endogenous reserves. They rely less on these stores during incubation because of their short fasting endurance. For example, endogenous reserves account for only 17 percent of the energy used by nesting blue-winged teal, and females lose only 15 percent of their body mass because they spend more time off the nest feeding.
Sources of abundant, high-quality food are critical to ducks during incubation because feeding time is restricted and they rely little on endogenous reserves. For approximately four weeks, females incubate their eggs in relative silence. Then, one or two days before hatching, clicking and peeping sounds are emitted from the eggs. Small cracks appear on the surface of each egg as the hatchlings strike the shell using their egg tooth—a tooth-like accessory on the bill that falls off shortly after hatching.
Vocalizations by the young help synchronize hatching and assist with imprinting because they stimulate vocalization by the female. The hatchlings finally emerge from the eggs after about 3 to 24 hours and dry in a few additional hours. After the brood hatches, the female frequently preens oil onto her breast, belly, and flanks, which is spread to the young. The female usually spends one night on the nest brooding the hatchlings prior to leaving the nest, and she will become increasingly vocal as the time approaches for exodus.
This behavior encourages her young to emerge from the nest and follow her closely as they explore their new surroundings. Ducks Unlimited project combatting Mississippi River flooding, protecting citizens and wetlands alike.
