TN I would advise you to have your temps stabilized for 24 hours before you out any eggs in. It gives you some opportunity to notice any idiosyncrasies your bator might have and to just get the feel of it. There is really nothing worse than checking your bator and thinking you have fried your babies. I ran mine for 2-3 days before I put the eggs in just to be sure. Incubating is fun and rewarding as long as nothing awful happens, I am looking g forward yo seeing your babies!!
