Often eggs in your incubator will be pipped or cracked, but the chicks just don’t hatch. There are many factors that contribute to this. Following is a list of these…
Causes Of Eggs Not Hatching
- Thin or porous shelled eggs.
- Improper storage of eggs before incubation, which may cause embryos to be positioned wrong. Store big end up and turn 3 times daily. Store at about 60 degrees.
- Eggs not turned during the first two weeks of incubation.
- Temperature is incorrect, too low for start of incubation or too high prior to hatching time.
- Humidity incorrect, too high for the start of incubation or too low prior to hatching.
- Insufficient water in water trays or channels.
- Bad ventilation – keep the vents open.
- Infection or disease caused by a bad egg or dirty incubator that wasn’t properly cleaned and disinfected.
Tips To Make Sure Eggs Hatch Every Time
- Choose incubation eggs carefully.
- Avoid incubating eggs that have thin or porous shells. Check carefully for cracks in eggs. Sometimes they are hairline and hard to see.
- If keeping eggs prior to incubation then store in the correct conditions and position.
- Turn eggs regularly prior to and during incubation (no egg turning in final three days of incubation). /li>
- Make sure eggs are stored and placed in the incubator with the small end facing down.
- Regularly check the temperature in the incubator.
- Try to maintain the correct temperature in the incubator at all times. Check it every couple hours if possible.
- Regularly check the humidity in the incubator.
- Try to maintain the correct humidity levels in the incubator at all time. Check it every couple hours if possible.
- Note that the required temperature and humidity levels are not the same throughout the whole of the incubation period.
- A wet bulb thermometer may be a good purchase to help accurately measure the humidity and temperature levels in the incubator. Check your hygrometer to make sure it is accurate.
- Check that the incubator is working correctly and has a constant temperature throughout the whole of the incubator. Do this before adding eggs and run at least 24 hours to make sure it stays consistent.
- Make sure that there is ventilation in the incubator and incubation room, but avoid drafts. A room with a thermostat is ideal.
- Check that breeding stock are healthy and free of infection and disease.
- Ensure that the incubator is thoroughly cleaned and disinfected prior to every use.
