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.

Remember!

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 decisions.

Remember!

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.
