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.
On day 18, remove the eggs from the turner and put them on the wire mesh that is normally included. Do not turn the eggs anymore. The chicks will hatch naturally, and it is important that you allow this to happen. It can take as much as a full day for a chick to get out of its egg, and you must not interfere.or those new to hatching chicken eggs, if your incubator does not have an automatic egg turner, you will have to do this yourself, three times a day, by hand.
