yeah, not really too big of an issue. I let them settle in and come to room temp, then go one with it. Like they said, get them that morning, set them that night. Have placed them right from the box to the bator too, really notice no difference. I also candle them on arrival and check the air cells to be sure they arent ruptured. If they are, setting them is a total waste of time as they will never hatch.
Main factor on them is their trip more than a set time frame before setting.
