Eggs of different terms of loading.

If you incubate eggs of different terms of loading (for example, with the interval of 3-6 days), during the entire period of incubation you have to keep the temperature of 37.6-37.8°Ñ (the reading of the wet thermometer of the psychrometer should be 27.5-28°Ñ).

Change the water more often. The fluff that falls onto the surface of water (the glass tank with water for the wet thermometer) during growing nestlings substantially reduces its evaporation and, consequently, the air humidity and because of this the nestlings that did not hatch out adhere in drying to the egg shell. To avoid this, change the water more often.
