OK, just discovered that my two incubators full of eggs are not getting the regular turning as they should. Seems neither of the turners are working properly. I am out of town as of today for a week and have no one to do the eggs twice a day. Can get some possibly done but not all. Will I loose these $250+ of eggs? What is the purpose of egg turning? I know the hens do this but just wondering the science behind it.
