When the reaction is complete, the endothermic gas must pass through a gas cooler (h) which uses ambient air or water to bring the temperature of the endothermic gas below 300 ÂºF. The gas must be cooled quickly to prevent undesired chemical reactions that create carbon fallout.
If you only have a few hens and need to wait a few days or weeks to collect enough eggs for your incubator, then keep them around 50-60 degrees and 75% relative humidity. (Best hatch rate is with eggs stored less than 1 week.) Do not put in refrigerator. Put them in an egg carton with the big end of the egg up.hicken eggs are incubated at 99 to 99.5 degrees. Chicken eggs incubate for 21 days. Your countdown for days starts when you put your eggs in your incubator. It does not start when the hen lays her eggs.
1 An automatic egg turner is placed in the incubator and will turn the eggs every 4 hours. 2  The final day of guinea fowl rotation is day 25 when the eggs no longer need to be turned. 3  When egg turning stops, the automatic egg timer can be removed.he Incubator. 1  Before incubating the guinea fowl eggs make sure that the incubator is thoroughly cleaned and disinfected. 2  Place the incubator in a room with a constant temperature. 3  The incubator should be placed on a flat surface. 4  Make sure that the incubator is placed away from drafts.
