How come chicks hatch late?

What are some of the possible reasons for late hatches of hatching eggs?
 Late hatches of hatching eggs can be caused by various factors, and identifying the specific reason for a particular situation may require careful observation and investigation. Here are some common reasons for late hatches:
  1. Incorrect Incubation Temperature: If the temperature in the incubator has not been pre-heated and/or not maintained within the appropriate range, it can lead to delayed hatching. Fluctuations in temperature can disrupt the development of the embryos, causing some to hatch later than others. Check your heating elements. DON'T FORGET TO CHECK THE INCUBATOR CALIBRATION !

  2. Inconsistent Humidity Levels: Inconsistent or incorrect humidity levels in the incubator can also affect the hatching time. High humidity can slow down development, while low humidity can cause the eggs to lose moisture too quickly, leading to delayed hatching. DON'T FORGET TO CHECK THE INCUBATOR CALIBRATION !

  3. Poor Egg Quality: The quality of the hatching eggs plays a significant role in when the embryos hatch. Eggs with defects, such as thin shells or improper storage, may develop more slowly and result in late hatches.

  4. Egg storage: Eggs stored for a long period of time can result in a larger hatch window and thus result in some chicks lagging in the hatch.
  5. Genetic Factors: Genetic factors can influence the development and hatching time of embryos. Some breeds or genetic lines may naturally have longer incubation periods.

  6. Incorrect Egg Turning: Regular and proper egg turning during incubation is essential to ensure that the embryos develop uniformly. If eggs are not turned correctly or consistently, it can lead to some embryos developing more slowly than others.

  7. Contamination or Disease: Bacterial or viral infections in the incubator or on the eggs themselves can disrupt the development of the embryos and cause late hatches.

  8. Stress or Disturbances: External disturbances or stress factors during incubation can lead to late hatches. This includes vibrations, loud noises, or frequent opening of the incubator.

  9. Incubation Period Variation: Some species or specific strains may naturally have variations in their incubation periods, resulting in delayed hatching. It's important to know the expected incubation period for the species or breed you are working with.

  10. Egg Positioning: The orientation of eggs in the incubator can affect hatching time. If eggs are not positioned correctly, i.e. point down, it can hinder the embryos' development and result in delayed hatches.

  11. Environmental Factors: Environmental conditions, such as ambient temperature and humidity, can influence the incubation process. Variations in the external environment can lead to variations in hatching times.

  12. Other factors such as temperature imbalances in the setter, leaking door seals, water on the floor (not with Dry hatch technology) eggs cooling down during transfer,...

To address late hatches, it's important to maintain proper incubation conditions, monitor egg quality, and practice good hygiene and sanitation in the incubation environment.


If late hatches persist or are a recurrent issue, it may be necessary to consult with an expert to identify and address the underlying cause.
