So we finally got our eggs in the incubator today! (18) we planned on doing it yesterday (monday) but couldn't because we were still trying to figure out the incubator. I wanted to do it on a Monday because then we could start lock down the friday before they hatch (day 18) and then not worry about them over the weekend. But since they started today, the 18th day will be on a Saturday and nobody will be here to take out the egg turner, raise the humidity, etc... I'm wondering, if we start lock down on Friday anyways, will they still hatch fine? It will be the 17th day and I've heard some say that's when theu start lockdown... is there a specific reason it has to be the 18th day? Also, during lockdown do you have to close any plugs in the incubator or leave them open?
