The thermal image shows how
temperature can vary across eggs in
a single tray, and the relatively lower
temperature above the air cell. Note the
increased heat for the eggs in the centre.
Adjust set times safely in 3-hour
increments up to a maximum of 15
hours. Do not adjust temperatures but
do keep checking to make sure the
adjusted time is correct.
Why collect this data?
Carrying out regular, thorough
checks will help eliminate problems
and make any investigations much
quicker. All hatchery staff should
be trained to spot the potential
issues outlined above, and use the
data collected to make informed
Data should be collected on:
✷ Eggshell temperature
✷ Egg water loss
✷ Chick yield
This information can give a clear
idea of what is happening in the
hatchery and enable any necessary
action to be pinpointed. The quicker
information is gathered and acted
upon, the quicker a successful hatching
programme can be implemented.
Monitoring performance means
improving performance which means
taking action. The result? Improved
chick output and performance on the
