I'm looking at getting a Little Giant Still Air Incubator and have read mixed reviews where some people do great and others do better with a cardboard box. I have no problem turning the eggs myself, but does it make THAT much of a difference to have an auto turner? Have people tried it both ways and have significantly greater success with one versus the other?? I understand that many people suggest reading the directions carefully, which we plan on doing, but are there any SUPER TOP SECRET tips that would be helpful in addition to the standard instructions? I've heard to ditch the thermometer it comes with and pick up something different. I also understand it doesn't come with a humidity gauge? Any suggestions would be welcome and helpful. I'm hoping to do my first hatch soon!!
