Hello! I have hatched a few clutches under broody hens, but my first incubator was delivered at my door as I was typing the title for this thread, so I'm new to the incubator game. I have been collecting eggs for a week and a half and have ended up with nearly 4 dozen eggs, although my incubator only holds 27. Since this is my first time, I'm thinking to put the oldest eggs in first so that if there's a problem early on, I can toss those eggs and have another batch ready to go. Or would it be better to use the freshest eggs first, and just collect more in case of a temp spike or other problem with the new incubator? I will, of course, start the incubator and let it run for a day or so before I put the eggs in. Also, I'm still waiting on my spare thermometer/hygrometers to be delivered later today.
