I have never hatched eggs before, but plan to start in the next month or so. I was looking at the brinsea eco 20. My question is: If I buy that with a manual turner, does that mean I have to manually turn EACH egg or is there a handle or something that I turn and it turns all of the eggs? Please help so I'll know what to buy. I would like to just get the manual if I don't have to turn each egg because of the cost, and then buy the automatic turner later on.
