This is my first time and I have it plugged in (after reading the directions a few times and spilling water everywhere and spiking the temp to 110) and it is regulating now... LOL. I bought this still air incubator and an egg turner but I didn't realize what still air meant. I know stupid right? So the fan is sold separately, do I go and buy the fan? Is it a necessity? I'm a single mom and would like to make this work without spending anymore money lol. I am going to attempt to hatch out 12 Delawares and 12 Barred Rocks and I don't want to unknowingly mess something up.
