I have the basic of basic incubators, LG still air from Tractor Supply for around $45, just completed first hatch attempt, got 2 of 8 hatched(should have been 3, I blame myself for this one, it made it to day 20/21 or so, I think the opening of the incubator on day 20 AND 21 caused this). They were shipped eggs, and I opened everyone that didnt hatch. 5 didnt develop at all(I would say this is either infertile eggs or got scrambled during shipping) So it should have been 3 of 8 on shipped eggs which to me sounds about the norm. I stuck more eggs in the incubator right after the first hatch, and I cleaned incubator out real good. 9 of my own fresh mutt EE eggs(Ameracauna rooster, my avatar, and my 2 red star hens), and 5 other eggs I picked up local from a local farm who breed's and MAY have some of the best blood lines and breeding stock that I will ever encounter, so these were 1 or 2 day old eggs, handled minimally. 2 Blue laced red wyandottes, 2 Auburn Java's(extremely rare), and 1 surprise egg she put in for me I am just wondering what advantage the moving air is compared to the still air. And if I run the temp higher with still air? I try to stay as close to 100.0 as I can, typically I check temp 10 times a day when I am home, and its typically 99.5-99.9 I was wondering if a little hotter would be better? I was wanting to shoot for 100.5 or so. So if someone can, let me know why I should want a fan please, since I feel I will have great success with the still air, this hatch will let me know. And. . . would it work for me by having the eggs inside a closed egg carton, egg carton sitting on its side in incubator and then when I need to turn eggs, I just flip carton over to sit on its other side. And then at day 18, take them out of carton and set them on bottom of incubator?? Will this work? turning 14 by hand seems like a task since I need to be quick so I dont lose so much heat.
