Emergency Preparations: It's COLD Outside! http://www.greenandhealthy.info/emergencyheat.html
Preheating eggs prior to incubation is an advantage when seeking optimum chick uniformity. For this reason, modular, single-stage incubation and high heating capacity are also recommended.
For incubators with a pre-heating programme
Use the pre-heating programme for the most uniform start to embryonic development. Starting the incubation cycle after internal egg temperature has reached 25 ˚C/77 ˚F (5 - 6 hours after preheat begins) reduces the risk of early mortality.
For incubators without a pre-heating programme
Pre-warm eggs to 25 ˚C in the setter room for a minimum of 12 hours. Trolleys loaded with eggs should be separated to ensure warm air circulates properly to all eggs.
Range in egg temperatures after heating with or without preheating in incubators with two different heating capacities. Egg weight varies between 50 - 70 grams.
