DEVELOPMENT CONTROL DURING THE INCUBATION PROCESS
For adequate embryonic development to occur during incubation, the physical conditions to which the fertile egg will be submitted must be controlled and monitored; these conditions are incubation temperature and humidity, and ventilation and egg turning
3 POST-INCUBATION FACTORS After hatching, the chicks must remain inside the transport boxes under adequate temperature and humidity conditions. Transport to the farms should preferably be carried out in climate-controlled trucks. It is recommended that this transport be carried out as soon as possible after

Failures in this process can lead to health problems due to immunological failure, in addition to contamination of eggs and/or newborns chicks when a vaccine is poorly administered (Oviedo-Rondón, 2013).
