Duck Eggs Hatching Early And Late

Eggs will often hatch early or late when placed in an incubator and there are a number of reasons for this.

Hi i have had 6 indian runner duck eggs in an incubator for 28.5 days now. One hatched two days early and is really healthy, eats and drinks. One we relised was off as the smell was bad. The other four are still in the incubator and now nearly 3 days late. Im really confused because one was two days early and the others haven’t hatched after 2days of the hatch date.
I have another 8 eggs in the incubator from a different set so i will be able to see if i have done something wrong, or if it was the eggs themselves.
But i was wondering what you think of the situation?

Thanks dan.

Hi Dan,
I am glad to hear that your duckling is healthy and doing well.
There are a number of reasons why eggs can hatch early and late.
Small eggs.
Improper egg storage.
Temperature too high in the incubator.
Humidity too low in the incubator.
Here are some handy tips to help prevent eggs hatching early;

Choose incubation eggs carefully.
Avoid incubating eggs that are too small.
If keeping eggs prior to incubation then store in the correct conditions (pay particular attention to temperature and humidity conditions).
Do not store eggs for more than 7 days before incubation.
If storing eggs before incubation, then turn the eggs regularly. http://www.farmingfriends.com/choosing-and-storing-eggs-before-incubation/
Regularly check the temperature in the incubator. http://www.farmingfriends.com/a-temperature-guide-for-different-species-of-birds-eggs-in-the-incubator/
Try to maintain the correct temperature in the incubator at all times.
Check the temperature in the incubator room is not too high.
Regularly check the humidity in the incubator. http://www.farmingfriends.com/humidity-levels-for-egg-incubation/
Try to maintain the correct humidity levels in the incubator at all time.
Note that the required temperature and humidity levels are not the same throughout the whole of the incubation period.
A wet bulb thermometer maybe a good purchase to help accurately measure the humidity and temperature levels in the incubator. http://www.farmingfriends.com/a-wet-bulb-thermometer/
Check that the incubator is working correctly and has a constant temperature throughout the whole of the incubator.
Reasons for a late hatch include:Large Eggs.

  1. Hi Joanne, Thanks for your comment, hope you had a good vacation.

    I would say that eggs can be incubated when they are up to 7 days old. They can still be incubated when older than 7 days old but the fertility rate begins to decrease the older the egg.

    If they have been in standing in water for long periods of time then they may not be viable as the water may have seeped through the porous shell and contaminated the egg.

    I have added your comment to the farmingfriends forum here http://farmingfriends.com/forums/topic.php?id=910

    Let me know what you decide to do with the eggs.
    Kind regards
