What are the reasons for rotten, exploded eggs during incubation

Eggs can become rotten or explode due to the following reasons:
  • Eggs become infected with infectious diseases from the parent flock (Salmonella bacteria).
  • Wet and dirty bedding or laying nests leads to infections of the egg with bacteria (e.g. Pseudomonas, E.coli, etc.).
  • Eggs have been wet prior to setting.
  • Improper egg cleaning procedures
  • a) Cleaning eggs in water which has a lower temperature than that of eggs
  • b) Cleaning eggs with a disinfection solution that has been prepared incorrectly not following the manufacturer recommendations.
  • High air humidity during egg storage.
  • Contamination during storage. Activities like sweeping or spraying water on the floor of the egg storage area can deposit large amounts of bacteria on the eggs.
  • Failure to clean incubators following an egg explosion leaves bacteria in the chamber that can contaminate other eggs.
