Although many poultry diseases can be prevented by good management and high standards of hygiene, a proper health management program is necessary to prevent pathogens from affecting the bird's health, to limit the effect of diseases, to protect the offspring and to prevent horizontal and/or vertical transmission of diseases.

Continuous flock monitoring by the flock attendant must be done, as he or she is the first person to notice any changes in the behavior or appearance of the bird, that may indicate disease challenges.

To control the flock's health status, the following should be monitored on a daily base:

- Feed and water intake

- Egg production

- Egg and egg shell quality

- Mortality and morbidity

- Bird behavior and appearance

- Respiratory noises

- Droppings

- External parasites
