I use a Hova-Bator 1602 and hand turn my eggs at least twice, but often 3-4 times a day. I made a chart that pretty well follows along with the manufacturers instructions that came with the incubator. I made a chart that I keep on a clipboard next to the incubator so that I can keep track of when to do things and to ensure that I have turned the eggs AT LEAST twice a day. Using this method I hatched 19 of 23 eggs, 16 of 19 eggs and 22 of 25 eggs - so far
. So I thought I'd share a link to my chart in case anyone else is interested in using it. (It's a pdf file) I make notes about how many I start with, how many I toss, etc. By hatch time, that sheet is a real mess.
